Supply voltages higher than 7.5 V (absolute maximum)canpermanentlydamagetheamplifier. Parameters that vary over supply voltage or temperature are shown in the Typical Characteristics section of this datasheet. 8.3.2 Rail-to-RailInput The specified input common-mode voltage range of the OPAx354 extends 100 mV beyond the supply rails. This extended range is achieved with a complementary input stage: an N-channel input differential pair in parallel with a P-channel differential pair, as shown in the Functional Block Diagram. The N-channel pair is active for input voltagesclosetothepositiverail,typically(V+) − 1.2Vto100mVabovethepositivesupply,whiletheP-channel pair is on for inputs from 100 mV below the negative supply to approximately (V+) − 1.2 V. There is a small transition region, typically (V+) − 1.5 V to (V+) − 0.9 V, in which both pairs are on. This 600-mV transition region vary ±500 mV with process variation. Therefore, the transition region (both input stages on) range from (V+) − 2 Vto(V+)− 1.5Vonthelowend,upto(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. 8.3.3 Rail-to-RailOutput AclassABoutputstagewithcommon-sourcetransistorsachievesrail-to-railoutput.Forhigh-impedanceloads(> 200Ω),theoutputvoltageswingistypically100mVfromthesupplyrails.With10-Ωloads,ausefuloutputswing isachievedwhilemaintaininghighopen-loopgain.Seethetypicalcharacteristiccurves, OutputVoltageSwingvs OutputCurrent(Figure20andFigure22). 8.3.4 OutputDrive The OPAx354 output stage supplies a continuous output current of ±100 mA and yet provide approximately 2.7 V of output swing on a 5-V supply, as shown in Figure 30.

However, all op amps may become unstable under certain conditions. Op amp configuration, gain, and load value are just 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 device output resistance, along with any additional load resistance, to create a pole in the small-signal response that degrades the phase margin. See the Frequency ResponseforVariousC typicalcharacteristiccurve(Figure13)fordetails. L The OPAx354 topology enhances its ability to drive capacitive loads. In unity gain, these op amps perform well with large capacitive loads. See the Recommended R vs Capacitive Load (Figure 14) and Frequency Response S vsCapacitiveLoad(Figure15)typicalcharacteristiccurvesfordetails. One method of improving capacitive load drive in the unity-gain configuration is to insert a 10-Ω to 20-Ω resistor in series with the output, as shown in Figure 35. This configuration significantly reduces ringing with large capacitive loads; see the Frequency Response vs Capacitive Load typical characteristic curve (Figure 15). However, if there is a resistive load in parallel with the capacitive load, R creates a voltage divider. This voltage S divisionintroducesaDCerrorattheoutputandslightlyreducesoutputswing.Thiserrormaybeinsignificant.For instance,withR =10kΩandR =20 Ω,thereisanerrorofapproximately0.2%attheoutput.

Low-voltage noise is important because photodiode capacitance causes the effective noise gain of the circuit to increase at high frequency. The key elements to a transimpedance design (as shown in Figure 36) are the expected diode capacitance [including the parasitic input common-mode and differential-mode input capacitance (2 + 2) pF for the OPAx354], the desired transimpedance gain (R ), and the gain-bandwidth product (GBW) for the OPAx354 (100 MHz, F typical).

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The OPAx354 family of devices is a CMOS, rail-to-rail I/O, high-speed, voltage-feedback operational amplifier designed for video, high-speed, and other applications. The OPAx354 family of devices is available as a single, dual, or quad op amp. The amplifier features a 100-MHz gain bandwidth, and 150-V/µs slew rate, but it is unity- gainstableandoperatesasa1-V/Vvoltagefollower. 9.2 Typical Application Wide gain bandwidth, low input bias current, low input voltage, and current noise make the OPAx354 family of devices an ideal wideband photodiode transimpedance amplifier. Low-voltage noise is important because photodiode capacitance causes the effective noise gain of the circuit to increase at high frequency. The key elements to a transimpedance design, as shown in Figure 37, are the expected diode capacitance, (which include the parasitic input common-mode and differential-mode input capacitance) the desired transimpedance gain,andthegain-bandwidth(GBW)fortheOPAx354familyofdevices(20MHz).Withthesethreevariablesset, the feedback capacitor value is set to control the frequency response.

Parameters that exhibit significant variance with regard to operating voltageortemperatureareshownTypicalCharacteristics. 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.. 11 Layout 11.1 Layout Guidelines Good high-frequency printed-circuit board (PCB) layout techniques must be employed for the OPAx354. 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 provides a means of dissipating heat that is generated innormaloperation. TIdoesnotrecommendusingsocketswithanyhigh-speedamplifier. A 10-nF ceramic bypass capacitor is the minimum recommended value; adding a 1-µF or larger tantalum capacitor in parallel is beneficial when driving a low-resistance load. Providing adequate bypass capacitance is essentialtoachievinglowharmonicandintermodulationdistortion. 11.2 Layout Example Figure39. OperationalAmplifierBoardLayoutforNoninvertingConfiguration 11.3 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 . Power dissipation is minimized by using the lowest possible power-supply voltage necessary to assure S O therequiredoutputvoltageswing. 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. AB-039 Power Amplifier Stress and Power Handling Limitations explains how to calculate or measure power dissipation with unusual signals and loads See www.ti.com for more details. 24 SubmitDocumentationFeedback Copyright©2002–2018,TexasInstrumentsIncorporated ProductFolderLinks:OPA354 OPA2354 OPA4354
OPA354,OPA2354,OPA4354 www.ti.com SBOS233G–MARCH2002–REVISEDAPRIL2018 Power Dissipation (continued) Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heat sink. For reliable operation, junction temperature must be limited to 150°C (maximum.) To estimate the margin of safety in a complete design, increase the ambient temperature until the thermal protection is triggered at 160°C. The thermal protection must trigger more than 35°C above the maximum expected ambient condition oftheapplication. 11.4 PowerPAD Thermally-Enhanced Package In addition to the regular 5-pin SOT-23 and 9-pin VSSOP packages, the single and dual versions of the OPAx354 also come in an 8-pin SOIC PowerPAD package. The 98-pin SO with PowerPAD is a standard size 8- pin SOIC package where the exposed leadframe on the bottom of the package is soldered directly to the PCB to create a low thermal resistance. This direct attachment enhances the OPAx354 power dissipation capability significantly, and eliminates the use of bulky heat sinks and slugs that are traditionally used in thermal packages. ThispackageiseasilymountedusingstandardPCBassemblytechniques. NOTE Because the 8-pin HSOP PowerPAD is pin-compatible with standard 8-pin SOIC packages, the OPA354 and OPA2354 can directly replace operational amplifiers in existing sockets. Soldering the PowerPAD to the PCB is always required, even with applications that have low power dissipation. This configuration provides the necessary thermalandmechanicalconnectionbetweentheleadframediepadandthePCB. The PowerPAD package is designed so that the leadframe die pad (or thermal pad) is exposed on the bottom of the device, as shown in Figure 40. This exposed die provides an extremely low thermal resistance (R ) path θJC between the die and the exterior of the package. The thermal pad on the bottom of the device can then be soldered directly to the PCB, using the PCB as a heat sink. In addition, plated-through holes (vias) provide a low thermalresistanceheatflowpathtothebacksideofthePCB.

SectionViewofaPowerPADPackage 11.5 PowerPAD Assembly Process The PowerPAD must be connected to the most negative supply voltage for the device, which is ground in single- supplyapplicationsandV−insplit-supplyapplications. Prepare the PCB with a top-side etch pattern, as shown in Figure 41. The exact land design may vary based on thespecificassemblyprocessrequirements.Theremustbeetchfortheleadsandetchforthethermalland. Place the recommended number of plated-through holes (or thermal vias) in the area of the thermal pad. These holes must be 13 mils (.013 in) in diameter. The holes are small so that solder wicking through the holes is not a problem during reflow. TI recommends a minimum of five holes for the 8-pin HSOP PowerPAD package, as showninFigure41.

REQUIRED: Thermal pad area 2.286mm x 2.286mm (90 mils x 90 mils) with 5 vias (via diameter = 13 mils) Figure41. 8-PinPowerPADPCBEtchandViaPattern TI recommends, but does not require, placing a small number of additional holes under the package and outside the thermal pad area. These holes provide additional heat paths between the copper thermal land and the ground plane. The holes may be larger because the holes are not in the area to be soldered, so wicking is not a problem.ThistechniqueisshowninFigure41. Connect all holes, including those within the thermal pad area and outside the pad area, to the internal ground planeorotherinternalcopperplaneforsingle-supplyapplications,andtoV−forsplit-supplyapplications. When laying out these holes, do not use the typical web or spoke via connection methodology, as shown in Figure42.Webconnectionshaveahighthermalresistanceconnectionthatisusefulforslowingtheheattransfer during soldering operations. This feature makes soldering the vias that have ground plane connections easier. However, in this application, low thermal resistance is desired for the most efficient heat transfer. Therefore, the holes under the PowerPAD package must make connection to the internal ground plane with a complete connectionaroundtheentirecircumferenceoftheplated-throughhole. Solid Via Web or Spoke Via RECOMMENDED NOTRECOMMENDED (due to poor heat conduction) Figure42. ViaConnection The top-side solder mask must leave the pad connections and the thermal pad area exposed. The thermal pad area must leave the 13-mil holes exposed. The larger holes outside the thermal pad area may be covered with a soldermask. Applysolderpastetotheexposedthermalpadareaandallofthepackagepins. With these preparatory steps in place, the PowerPAD device is placed in position and run through the solder reflow operation as any standard surface-mount component. This preparation and processing results in a part thatisproperlyinstalled.
