The devices are unity-gain stable and can operate on a single-supply voltage (2.5 V to 5.5 V), or a split-supply voltage (±1.25 V to ±2.75 V), making them highly versatile and easy to use. The OPAx354A-Q1 amplifiers are specified from 2.5 V to 5.5 V and over the automotive temperature range of –40°C to+125°C.

A complementary input stage (an N-channel input differential pair in parallel with a P-channel differential pair) achieves this extension. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.2 V to 100 mV above the positive supply, while the P-channel pair is on for inputs from 100 mV below the negative supply to approximately (V+) – 1.2 V. A small transition region exists, typically (V+) – 1.5 V to (V+) – 0.9 V, in which both pairs are on. This 600-mV transition region can vary ±500 mV with process variation. As a result, the transition region (both input stages on) range from (V+) – 2 V to (V+) – 1.5 V on the low end, up to(V+) –0.9Vto(V+) – 0.4Vonthehighend. A double-folded cascode adds the signal from the two input pairs and presents a differential signal to the class- ABoutputstage. 7.3.3 Rail-to-RailOutput The device uses a class-AB output stage with common-source transistors to achieve rail-to-rail output. For high- impedance loads (> 200 Ω), the output voltage swing is typically 100 mV from the supply rails. With 10-Ω loads, a user can achieve a useful output swing while maintaining high open-loop gain; see Figure 20 (Output Voltage SwingvsOutputCurrent). 7.3.4 OutputDrive The OPAx354-Q1 output stage supplies a continuous output current of ±100 mA and still provide approximately 2.7-Voutputswingona5-Vsupply,asshowninFigure30.

ParallelOperation The OPAx354-Q1 family of devices provides peak currents up to 200 mA, which correspond to the typical short- circuit current.

A back-terminated transmission line does not exhibit a capacitive load to the driver.

RGBCableDriver 7.3.6 DrivingAnalog-to-DigitalConverters The OPAx354-Q1 family of op-amps offers a 60-ns settling time to 0.01%, which makes the devices a viable option for driving high- and medium-speed sampling ADCs and reference circuits. The OPAx354-Q1 family of devices provides an effective means of buffering the input capacitance and resulting charge injection of the ADC while providing signal gain. The OPAx354-Q1 family of devices is designed for applications requiring high DC accuracy. Figure 34 shows the OPAx354-Q1 family of devices driving an ADC.

However, all op-amps under certain conditions can become unstable. Op amp configuration, gain, and load value are a few of the factors to consider when determining stability. An op amp in unity-gain configuration is most susceptible to the effects of capacitive loading. The capacitive load reacts with the output resistance of the op amp, along with any additional load resistance, to create a pole in the small-signal response that degrades the phase margin. For details, see Figure15(FrequencyResponsevsCapacitiveLoad.) The OPAx354-Q1 topology enhances the ability of the device to drive capacitive loads. In unity gain, these op- amps perform well with large capacitive loads. For details see Figure 14, Recommended R vs Capacitive Load, S andFigure15,FrequencyResponsevsCapacitiveLoad. Insert a 10-Ω to 20-Ω resistor in series with the output to improve capacitive laod drive in the unity-gain configuration, as shown in Figure 35. This configuration significantly reduces ringing with large capacitive loads; see Figure 15 (Frequency Response vs Capacitive Load.) However, if a resistive load is in parallel with the capacitive load, R creates a voltage divider. This configuration introduces a DC error at the output and slightly S reduces output swing. This error may be insignificant. For example, if R = 10 kΩ and R = 20 Ω, the error at the L S outputisapproximately0.2%. V+ R S OPA354-Q1 V OUT V IN R C L L Figure35.

For lowest noise, select R to create the total required gain. Using a lower value for R and adding gain (FB) (FB) after the transimpedance amplifier generally produces poorer noise performance. The noise produced by R increases with the square-root of R , whereas the signal increases linearly. Therefore, signal-to-noise (FB) (FB) ratioimproveswhenalltherequiredgainisplacedinthetransimpedancestage. 2. Minimize photodiode capacitance and stray capacitance at the summing junction (inverting input). This capacitance causes the voltage noise of the op amp to be amplified (increasing amplification at high frequency). Using a low-noise voltage source to reverse-bias a photodiode can significantly reduce the capacitance. Smaller photodiodes have lower capacitance. Use optics to concentrate light on a small photodiode. 3. Noise increases with increased bandwidth. Limit the circuit bandwidth to only that required. Use a capacitor acrosstheR tolimitbandwidth,evenifnotrequiredforstability. (FB) 4. Circuit board leakage can degrade the performance of an otherwise well-designed amplifier.

DrivingtheADS8326 8.2.4 ActiveFilter The OPAx354-Q1 family of devices is designed for active filter applications that require a wide bandwidth, fast slew rate, low-noise, single-supply operational amplifier. Figure 42 shows a 500 kHz, second-order, low-pass filter using the multiple-feedback (MFB) topology. The components are selected to provide a maximally-flat Butterworth response. Beyond the cutoff frequency, roll-off is –40 dB/dec. The Butterworth response is designed for applications requiring predictable gain characteristics, suchastheanti-aliasingfilterusedinfrontofanADC. One point to observe when considering the MFB filter is that the output is inverted relative to the input. If this inversion is not required, or not desired, a noninverting output can be achieved through one of the following options: 1. Addinganinvertingamplifier 2. Addinganadditionalsecond-orderMFBstage 3. Usinganoninvertingfiltertopology,suchastheSallen-Key(seeFigure43). MFB and Sallen-Key, low-pass and high-pass filter synthesis is accomplished using TI’s FilterPro™ program.

Parameters that can exhibit significant variance with regard to operatingvoltageortemperatureareshownintheTypicalCharacteristicssection. CAUTION Supply voltages larger than 7.5 V can permanently damage the device (see the AbsoluteMaximumRatingstable). Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high- impedance power supplies. For more detailed information on bypass capacitor placement, see the Layout Guidelinessection.

OPA354A-Q1,OPA2354A-Q1,OPA4354-Q1 SBOS492F–JUNE2009–REVISEDMAY2018 www.ti.com 9.1 Power Dissipation Power dissipation depends on power-supply voltage, signal and load conditions. With dc signals, power dissipation is equal to the product of output current times the voltage across the conducting output transistor (V – V ). Minimize power dissipation by using the lowest possible power-supply voltage required to ensure the S O requiredoutputvoltageswing. For resistive loads, the maximum power dissipation occurs at a DC output voltage of one-half the power-supply voltage. Dissipation with AC signals is lower. The Power Amplifier Stress and Power Handling Limitations application bulletin from www.ti.com explains how to calculate or measure power dissipation with unusual signals andloads. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heat sink. For reliable operation, limit junction temperature to 150°C, maximum. To estimate the margin of safety in a complete design, increase the ambient temperature to trigger the thermal protection at 160°C. The thermal protectionmusttriggermorethan35°Cabovethemaximumexpectedambientconditionoftheapplication. 10 Layout 10.1 Layout Guidelines Use good high-frequency printed circuit board (PCB) layout techniques for the OPAx354-Q1 family of devices. Generous use of ground planes, short and direct signal traces, and a suitable bypass capacitor located at the V+ pin ensure clean, stable operation. Large areas of copper provide a means of dissipating heat that is generated in normal operation. Sockets are not recommended for use with any high-speed amplifier. A 10-nF ceramic bypass capacitor is the minimum recommended value; adding a 1-μF or larger tantalum capacitor in parallel can be beneficial when driving a low-resistance load. Providing adequate bypass capacitance is essential to achievingverylowharmonicandintermodulationdistortion. Forbestoperationalperformanceofthedevice,usegoodPCBlayoutpractices,including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low- impedancepowersourceslocaltotheanalogcircuitry. – Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single- supplyapplications. • Separate grounding for analog and digital portions of the circuitry is one of the simplest and most effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. For moredetailedinformation,seeCircuitBoardLayoutTechniques. • To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicularly is much betterthancrossinginparallelwiththenoisytrace. • Place the external components as close to the device as possible. Keeping RF and RG close to the invertinginputminimizesparasiticcapacitance,asshowninFigure44. • Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitivepartofthecircuit. • Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduceleakagecurrentsfromnearbytracesthatareatdifferentpotentials. 26 SubmitDocumentationFeedback Copyright©2009–2018,TexasInstrumentsIncorporated ProductFolderLinks:OPA354A-Q1 OPA2354A-Q1 OPA4354-Q1
