OPA134,OPA2134,OPA4134 SBOS058A–DECEMBER1997–REVISEDOCTOBER2015 www.ti.com 7 Detailed Description 7.1 Overview The OPA134 series are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This, in combination with high output drive capability and excellent DC performance, allows for use in a wide variety of demanding applications. In addition, the OPA134 has a wide output swing, to within 1 V of therails,allowingincreasedheadroomandmakingitidealforuseinanyaudiocircuit. 7.2 Functional Block Diagram Input Offset Adjust (OPA134 only) +IN + Output -IN – Input Offset Compensation Adjust (OPA134 only) 7.3 Feature Description 7.3.1 TotalHarmonicDistortion The OPA134 series of operational amplifiers have excellent distortion characteristics. THD+Noise is below 0.0004%throughouttheaudiofrequencyrange,20Hzto20kHz,witha2-kΩ load.Inaddition,distortionremains relatively flat through its wide output voltage swing range, providing increased headroom compared to other audioamplifiers,includingtheOP176/275. Headroom is a subjective measurement, and can be thought of as the maximum output amplitude allowed while still maintaining a low level of distortion. In an attempt to quantify headroom, TI defines very low distortion as 0.01%. Headroom is expressed as a ratio which compares the maximum allowable output voltage level to a standard output level (1 mW into 600 Ω, or 0.7746 Vrms). Therefore, OPA134 series of operational amplifiers, which have a maximum allowable output voltage level of 11.7 Vrms (THD+Noise < 0.01%), have a headroom specificationof23.6dBu.SeeFigure4. 7.3.2 DistortionMeasurements The distortion produced by OPA134 series of operational amplifiers is below the measurement limit of all known commercially-availableequipment.However,aspecialtestcircuitcanextendthemeasurementcapabilities. Operational amplifier distortion can be considered an internal error source which can be referred to the input. Figure 27 shows a circuit which causes the operational amplifier distortion to be 101 times greater than that which the operational amplifier normally produces. The addition of R3 to the otherwise standard non-inverting amplifier configuration alters the feedback factor or noise gain of the circuit. The closed-loop gain is unchanged, butthefeedbackavailableforerrorcorrectionisreducedbyafactorof101,thusextendingtheresolutionby101.

DistortionTestCircuit This technique can be verified by duplicating measurements at high gain or high frequency, where the distortion is within the measurement capability of the test equipment. Measurements for this data sheet were made with an Audio Precision distortion and noise analyzer, which greatly simplifies repetitive measurements. The measurementtechniquecan,however,beperformedwithmanualdistortionmeasurementinstruments. 7.3.3 SourceImpedanceandDistortion For lowest distortion with a source or feedback network with an impedance greater than 2 kΩ, the impedance seenbythepositiveandnegativeinputsinnoninvertingapplicationsshouldbematched.Thep-channelJFETsin the FET input stage exhibit a varying input capacitance with applied common-mode input voltage. In inverting configurations, the input does not vary with input voltage, because the inverting input is held at virtual ground. However, in noninverting applications the inputs do vary, and the gate-to-source voltage is not constant. The effect is increased distortion due to the varying capacitance for unmatched source impedances greater than 2 kΩ. To maintain low distortion, match unbalanced source impedance with the appropriate values in the feedback network as shown in Figure 28. Of course, the unbalanced impedance may be from gain-setting resistors in the feedback path. If the parallel combination of R1 and R2 is greater than 2 kΩ, use a matching impedance on the noninvertinginput.Asalways,minimizeresistorvaluestoreducetheeffectsofthermalnoise.

ImpedanceMatchingforMaintainingLowDistortioninNon-InvertingCircuits 7.3.4 PhaseReversalProtection The OPA134 series of operational amplifiers are free from output phase-reversal problems. Many audio operational amplifiers, such as the OP176, exhibit phase-reversal of the output when the input common-mode voltage range is exceeded. This can occur in voltage-follower circuits, causing serious problems in control loop applications. The OPA134 series operational amplifiers are free from this undesirable behavior even with inputs of10-Vbeyondtheinputcommon-moderange.

The limit current decreases with increasingtemperature,asshowninFigure19. 7.4 Device Functional Modes 7.4.1 NoisePerformance Circuit noise is determined by the thermal noise of external resistors and operational amplifier noise. Operational amplifier noise is described by two parameters: noise voltage and noise current. The total noise is quantified by theequation: V (total)= (i R )2e 2 +4kTR n n S n S (1) With low source impedance, the current noise term is insignificant and voltage noise dominates the noise performance.Athighsourceimpedance,thecurrentnoisetermbecomesthedominantcontributor. Low-noise bipolar operational amplifiers such as the OPA27 and OPA37 provide low voltage noise at the expense of a higher current noise. However, OPA134 series operational amplifiers provide both low voltage noise and low current noise. This provides optimum noise performance over a wide range of sources, including reactive source impedances; refer to Figure 6. Above 2-kΩ source resistance, the operational amplifier contributes little additional noise; the voltage and current terms in the total noise equation become insignificant and the source resistance term dominates. Below 2 kΩ, operational amplifier voltage noise dominates over the resistornoise,butcomparesfavorablywithotheraudiooperationalamplifierssuchastheOP176. 14 SubmitDocumentationFeedback Copyright©1997–2015,TexasInstrumentsIncorporated ProductFolderLinks:OPA134 OPA2134 OPA4134

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The OPA134 series operational amplifiers are unity-gain stable, and suitable for a wide range of audio and general-purpose applications. All circuitry is independent in the dual version, assuring normal behavior when one amplifierinapackageisoverdrivenorshort-circuited.Powersupplypinsshouldbebypassedwith10-nFceramic capacitorsorlargertominimizepowersupplynoise. 8.1.1 OperatingVoltage The OPA134 series of operational amplifiers operate with power supplies from ±2.5 V to ±18 V with excellent performance. Although specifications are production tested with ±15-V supplies, most behavior remains unchanged throughout the full operating voltage range. Parameters which vary significantly with operating voltageareshowninTypicalCharacteristics. 8.1.2 OffsetVoltageTrim Offset voltage of OPA134 series amplifiers is laser-trimmed, and usually requires no user adjustment. The OPA134 (single operational amplifier version) provides offset trim connections on pins 1 and 8, identical to 5534 amplifiers. Offset voltage can be adjusted by connecting a potentiometer as shown in Figure 29. This adjustment should be used only to null the offset of the operational amplifier, not to adjust system offset or offset produced by the signal source. Nulling offset could change the offset voltage drift behavior of the operational amplifier. Whileitisnotpossibletopredicttheexactchangeindrift,theeffectisusuallysmall.

Parameters that can exhibit significant variance with regard to operating voltage or temperature arepresentedintheTypicalCharacteristics. CAUTION Supply voltages larger than 36 V can permanently damage the device; see the AbsoluteMaximumRatings. Place 10-nF 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 Guidelines. 10 Layout 10.1 Layout Guidelines Forbestoperationalperformanceofthedevice,usegoodPCBlayoutpractices,including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole and operational amplifier itself. Bypass capacitors are used to reduce the coupled noise by providing low-impedance power sourceslocaltotheanalogcircuitry. – Connect low-ESR, 10-nF 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 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 more detailed information refer to CircuitBoardLayoutTechniques,SLOA089. • In order 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 perpendicular is much better as opposedtoinparallelwiththenoisytrace. • Place the external components as close to the device as possible. As shown in Layout Example, keeping RF andRGclosetotheinvertinginputminimizesparasiticcapacitance. • 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 reduce leakagecurrentsfromnearbytracesthatareatdifferentpotentials. • CleaningthePCBfollowingboardassemblyisrecommendedforbestperformance. • Any precision integrated circuit may experience performance shifts due to moisture ingress into the plastic package. Following any aqueous PCB cleaning process, baking the PCB assembly is recommended to remove moisture introduced into the device packaging during the cleaning process. A low temperature, post cleaningbakeat85°Cfor30minutesissufficientformostcircumstances. 18 SubmitDocumentationFeedback Copyright©1997–2015,TexasInstrumentsIncorporated ProductFolderLinks:OPA134 OPA2134 OPA4134
