    DESCRIPTIONThe OPA134 series are ultra-low distortion, low noiseoperational amplifiers fully specified for audio appli-cations. A true FET input stage was incorporated toprovide superior sound quality and speed for excep-tional audio performance. This in combination withhigh output drive capability and excellent dc perfor-mance allows use in a wide variety of demandingapplications. In addition, the OPA134s wide outputswing, to within 1V of the rails, allows increasedheadroom making it ideal for use in any audio circuit.

    OPA134 op amps are easy to use and free from phaseinversion and overload problems often found in com-mon FET-input op amps. They can be operated from2.5V to 18V power supplies. Input cascode cir-cuitry provides excellent common-mode rejection andmaintains low input bias current over its wide inputvoltage range, minimizing distortion. OPA134 seriesop amps are unity-gain stable and provide excellentdynamic behavior over a wide range of load condi-tions, including high load capacitance. The dual and

    quad versions feature completely independent cir-cuitry for lowest crosstalk and freedom from interac-tion, even when overdriven or overloaded.

    Single and dual versions are available in 8-pin DIPand SO-8 surface-mount packages in standard con-figurations. The quad is available in 14-pin DIP andSO-14 surface mount packages. All are specified for40C to +85C operation. A SPICE macromodel isavailable for design analysis.

    ELECTROSTATICDISCHARGE SENSITIVITY

    This integrated circuit can be damaged by ESD. Burr-Brown

    recommends that all integrated circuits be handled with

    appropriate precautions. Failure to observe proper handling

    and installation procedures can cause damage.

    ESD damage can range from subtle performance degrada-

    tion to complete device failure. Precision integrated circuits

    may be more susceptible to damage because very small

    parametric changes could cause the device not to meet its

    published specifications.

    APPLICATIONS INFORMATIONOPA134 series op amps are unity-gain stable and suitable

    for a wide range of audio and general-purpose applications.

    All circuitry is completely independent in the dual version,

    assuring normal behavior when one amplifier in a package

    is overdriven or short-circuited. Power supply pins should

    be bypassed with 10nF ceramic capacitors or larger tominimize power supply noise.

    OPERATING VOLTAGE

    OPA134 series op amps operate with power supplies from

    2.5V to 18V with excellent performance. Althoughspecifications are production tested with 15V supplies,most behavior remains unchanged throughout the full

    operating voltage range. Parameters which vary signifi-

    cantly with operating voltage are shown in the typical

    performance curves.

    OFFSET VOLTAGE TRIM

    Offset voltage of OPA134 series amplifiers is laser trimmed

    and usually requires no user adjustment. The OPA134(single op amp 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 1. This adjustment should be used only to

    null the offset of the op amp, not to adjust system offset or

    offset produced by the signal source. Nulling offset could

    change the offset voltage drift behavior of the op amp.

    While it is not possible to predict the exact change in drift,

    the effect is usually small.

    TOTAL HARMONIC DISTORTION

    OPA134 series op amps have excellent distortion character-

    istics. THD+Noise is below 0.0004% throughout the audio

    frequency range, 20Hz to 20kHz, with a 2k load. Inaddition, distortion remains relatively flat through its

    wide output voltage swing range, providing increased head-

    room compared to other audio amplifiers, including the

    OP176/275.

    In many ways headroom is a subjective measurement. It can

    be thought of as the maximum output amplitude allowed

    while still maintaining a very low level of distortion. In an

    attempt to quantify headroom, we have defined very low

    distortion as 0.01%. Headroom is expressed as a ratio

    which compares the maximum allowable output voltagelevel to a standard output level (1mW into 600, or0.7746Vrms). Therefore, OPA134 series op amps, which

    have a maximum allowable output voltage level of 11.7Vrms

    (THD+Noise < 0.01%), have a headroom specification of

    23.6dBu. See the typical curve Headroom - Total Harmonic

    Distortion + Noise vs Output Amplitude.

    DISTORTION MEASUREMENTS

    The distortion produced by OPA134 series op amps is below

    the measurement limit of all known commercially available

    equipment. However, a special test circuit can be used to

    extend the measurement capabilities.

    Op amp distortion can be considered an internal error source

    which can be referred to the input. Figure 2 shows a

    circuit which causes the op amp distortion to be 101 times

    greater than normally produced by the op amp. 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, but the feedback

    available for error correction is reduced by a factor of 101,

    thus extending the resolution by 101. Note that the input

    signal and load applied to the op amp are the same as with

    conventional feedback without R3. The value of R3 should

    be kept small to minimize its effect on the distortion mea-

    surements.Validity of this technique can be verified by duplicating

    measurements at high gain and/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/noise analyzer which

    greatly simplifies such repetitive measurements. The mea-

    surement technique can, however, be performed with manual

    distortion measurement instruments.

    SOURCE IMPEDANCE AND DISTORTION

    For lowest distortion with a source or feedback network

    which has an impedance greater than 2k, the impedanceseen by the positive and negative inputs in noninverting

    applications should be matched. The p-channel JFETs in theFET input stage exhibit a varying input capacitance with

    applied common-mode input voltage. In inverting configu-

    rations the input does not vary with input voltage since 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 2k.

    To maintain low distortion, match unbalanced source im-

    pedance with appropriate values in the feedback network as

    shown in Figure 3. Of course, the unbalanced impedance

    may be from gain-setting resistors in the feedback path. If

    the parallel combination of R1and R2is greater than 2k, amatching impedance on the noninverting input should be

    used. As always, resistor values should be minimized to

    reduce the effects of thermal noise.

    FIGURE 3. Impedance Matching for Maintaining Low

    Distortion in Non-Inverting Circuits.

    NOISE PERFORMANCE

    Circuit noise is determined by the thermal noise of external

    resistors and op amp noise. Op amp noise is described by

    two parametersnoise voltage and noise current. The total

    noise is quantified by the equation:

    With low source impedance, the current noise term is

    insignificant and voltage noise dominates the noise perfor-

    mance. At high source impedance, the current noise term

    becomes the dominant contributor.

    Low noise bipolar op amps such as the OPA27 and OPA37

    provide very low voltage noise at the expense of a higher

    current noise. However, OPA134 series op amps are unique

    in providing very low voltage noise and very low current

    noise. This provides optimum noise performance over a

    wide range of sources, including reactive source imped-

    ances, refer to the typical curve, Voltage Noise vs Source

    Resistance. Above 2k source resistance, the op ampcontributes little additional noisethe voltage and current

    terms in the total noise equation become insignificant andthe source resistance term dominates. Below 2k, op ampvoltage noise dominates over the resistor noise, but com-

    pares favorably with other audio op amps such as OP176.

    PHASE REVERSAL PROTECTION

    OPA134 series op amps are free from output phase-reversal

    problems. Many audio op amps, such as OP176, exhibit

    phase-reversal of the output when the input common-mode

    voltage range is exceeded. This can occur in voltage-fol-

    lower circuits, causing serious problems in control loop

    applications. OPA134 series op amps are free from this

    undesirable behavior even with inputs of 10V beyond the

    input common-mode range.

    POWER DISSIPATION

    OPA134 series op amps are capable of driving 600loadswith power supply voltage up to 18V. Internal powerdissipation is increased when operating at high supply

    voltages. Copper leadframe construction used in OPA134

    series op amps improves heat dissipation compared to con-

    ventional materials. Circuit board layout can also help

    minimize junction temperature rise. Wide copper traces help

    dissipate the heat by acting as an additional heat sink.

    Temperature rise can be further minimized by soldering the

    devices to the circuit board rather than using a socket.

    OUTPUT CURRENT LIMIT

    Output current is limited by internal circuitry to approxi-

    mately 40mA at 25C. The limit current decreases withincreasing temperature as shown in the typical performance

    curve Short-Circuit Current vs Temperature.
