BU7241G BU7241SG BU7242xxx BU7242Sxxx BU7244xx BU7244Sxx Datasheet Description of electrical characteristics Described below are descriptions of the relevant electrical terms used in this datasheet. Items and symbols used are also shown. Note that item name and symbol and their meaning may differ from those on another manufacturer’s document or general document. 1. Absolute maximum ratings Absolute maximum rating items indicate the condition which must not be exceeded. Application of voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of characteristics. (1) Supply Voltage (VDD/VSS) Indicates the maximum voltage that can be applied between the VDD terminal and VSS terminal without deterioration or destruction of characteristics of internal circuit. (2) Differential Input Voltage (V ) ID Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging the IC. (3) Input Common-mode Voltage Range (V ) ICM Indicates the maximum voltage that can be applied to the non-inverting and inverting terminals without deterioration or destruction of electrical characteristics. Input common-mode voltage range of the maximum ratings does not assure normal operation of IC. For normal operation, use the IC within the input common-mode voltage range characteristics. (4) Power Dissipation (P ) D Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25℃ (normal temperature). As for package product, P is determined by the temperature that can be permitted by the IC in D the package (maximum junction temperature) and the thermal resistance of the package. 2. Electrical characteristics (1) Input Offset Voltage (V ) IO Indicates the voltage difference between non-inverting terminal and inverting terminals. It can be translated into the input voltage difference required for setting the output voltage at 0 V. (2) Input Offset Current (I ) IO Indicates the difference of input bias current between the non-inverting and inverting terminals. (3) Input Bias Current (I ) B Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias currents at the non-inverting and inverting terminals. (4) Supply Current (I ) DD Indicates the current that flows within the IC under specified no-load conditions. (5) Maximum Output Voltage(High) / Maximum Output Voltage(Low) (V /V ) OH OL Indicates the voltage range of the output under specified load condition. It is typically divided into maximum output voltage high and low. Maximum output voltage high indicates the upper limit of output voltage. Maximum output voltage low indicates the lower limit. (6) Large Signal Voltage Gain (A ) V Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal and inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage. Av = (Output voltage) / (Differential Input voltage) (7) Input Common-mode Voltage Range (V ) ICM Indicates the input voltage range where IC normally operates. (8) Common-mode Rejection Ratio (CMRR) Indicates the ratio of fluctuation of input offset voltage when the input common mode voltage is changed. It is normally the fluctuation of DC. CMRR = (Change of Input common-mode voltage)/(Input offset fluctuation) (9) Power Supply Rejection Ratio (PSRR) Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. It is normally the fluctuation of DC. PSRR = (Change of power supply voltage)/(Input offset fluctuation) (10) Output Source Current / Output Sink Current (I /I ) SOURCE SINK The maximum current that can be output under specific output conditions, it is divided into output source current and output sink current. The output source current indicates the current flowing out of the IC, and the output sink current the current flowing into the IC. (11) Slew Rate (SR) Indicates the ratio of the change in output voltage with time when a step input signal is applied. (12) Gain Bandwidth (GBW) The product of the open-loop voltage gain and the frequency at which the voltage gain decreases 6dB/octave. www.rohm.com TSZ02201-0RAR0G200240-1-2 © 2013 ROHM Co., Ltd.

BU7241G BU7241SG BU7242xxx BU7242Sxxx BU7244xx BU7244Sxx Datasheet Power Dissipation Power dissipation (total loss) indicates the power that the IC can consume at T =25°C (normal temperature). As the IC A consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and consumable power. Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold resin or lead frame of the package. Thermal resistance, represented by the symbol θ °C/W, indicates this heat dissipation JA capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance. Figure 78(a) shows the model of the thermal resistance of a package. The equation below shows how to compute for the Thermal resistance (θ ), given the ambient temperature (T ), maximum junction temperature (T ), and power dissipation JA A Jmax (P ). D θ = (T －T ) / P °C/W JA Jmax A D The Derating curve in Figure 78 (b) indicates the power that the IC can consume with reference to ambient temperature. Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal resistance (θ ), which depends on the chip size, power consumption, package, ambient temperature, package condition, JA wind velocity, etc. This may also vary even when the same of package is used. Thermal reduction curve indicates a reference value measured at a specified condition. Figure 78(c) to 78(h) shows an example of the derating curve for BU7241G, BU7241SG, BU7242xxx, BU7242Sxxx, BU7244xx, BU7244Sxx.

BU7241G BU7241SG BU7242xxx BU7242Sxxx BU7244xx BU7244Sxx Datasheet Operational Notes 1. Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. The absolute maximum rating of the P stated in this specification is when D the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the P rating. D 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. 11. Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. www.rohm.com TSZ02201-0RAR0G200240-1-2 © 2013 ROHM Co., Ltd.

BU7241G BU7241SG BU7242xxx BU7242Sxxx BU7244xx BU7244Sxx Datasheet Operational Notes – continued 12. Regarding the Input Pin of the IC In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The operation of these parasitic elements can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an input pin lower than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input pins when no power supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the input pins have voltages within the values specified in the electrical characteristics of this IC. VDD 13. Unused Circuits When there are unused op-amps, it is recommended that they are connected as in Figure 79, setting the non-inverting input terminal to a potential within the Input Common-mode Voltage Range (VICM). Keep this potential in VICM VICM 14. Input Voltage Applying VDD+0.3V to the input terminal is possible without causing deterioration of the electrical characteristics or destruction. However, this does not ensure normal circuit operation. Please note that the VSS circuit operates normally only when the input voltage is within the common mode input voltage range of the electric characteristics. Figure 79. Example of Application Circuit for Unused Op-amp 15. Power Supply(single/dual) The operational amplifier operates when the voltage supplied is between VDD and VSS. Therefore, the single supply operational amplifiers can be used as dual supply operational amplifiers as well. 16. Output Capacitor If a large capacitor is connected between the output pin and VSS pin, current from the charged capacitor will flow into the output pin and may destroy the IC when the VDD pin is shorted to ground or pulled down to 0V. Use a capacitor smaller than 0.1uF between output pin and VSS pin. 17. Oscillation by Output Capacitor Please pay attention to the oscillation by output capacitor and in designing an application of negative feedback loop circuit with these ICs. 18. Latch up Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up and protect the IC from abnormaly noise. 19. Decupling Capacitor Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier. 20. Radiation Land The VSON008X2030 package has a radiation land in the center of the back. Please connect to VSS potenital or don't connect to other terminal. www.rohm.com TSZ02201-0RAR0G200240-1-2 © 2013 ROHM Co., Ltd. All rights reserved. 35/44 03.Dec.2014 Rev.003 TSZ22111･15･001

If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4. The Products are not subject to radiation-proof design. 5. Please verify and confirm characteristics of the final or mounted products in using the Products. 6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied, confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual ambient temperature. 8. Confirm that operation temperature is within the specified range described in the product specification. 9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document. Precaution for Mounting / Circuit board design 1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product performance and reliability. 2. In principle, the reflow soldering method must be used on a surface-mount products, the flow soldering method must be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products, please consult with the ROHM representative in advance.
