DESCRIPTION

The OPA134 series are ultra-low distortion, low noise
operational amplifiers fully specified for audio appli­cations. A true FET input stage was 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 use in a wide variety of demanding
applications. In addition, the OPA134’s wide output
swing, to within 1V of the rails, allows increased
headroom making it ideal for use in any audio circuit.

OPA134 op amps are easy to use and free from phase
inversion and overload problems often found in com­mon FET-input op amps. They can be operated from
±2.5V to ±18V power supplies. Input cascode cir-
cuitry provides excellent common-mode rejection and
maintains low input bias current over its wide input
voltage range, minimizing distortion. OPA134 series
op amps are unity-gain stable and provide excellent
dynamic behavior over a wide range of load condi­tions, including high load capacitance. The dual and
quad versions feature completely independent cir­cuitry for lowest crosstalk and freedom from interac­tion, even when overdriven or overloaded.

Single and dual versions are available in 8-pin DIP
and SO-8 surface-mount packages in standard con­figurations. The quad is available in 14-pin DIP and
SO-14 surface mount packages. All are specified for
–40°C to +85°C operation. A SPICE macromodel is
available for design analysis.

DISCHARGE 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 degrada­tion 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 INFORMATION

OPA134 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 to
minimize power supply noise.

OPERATING VOLTAGE

OPA134 series op amps operate with power supplies from
±2.5V to ±18V with excellent performance. Although
specifications are production tested with ±15V supplies,
most behavior remains unchanged throughout the full
operating voltage range. Parameters which vary signifi­cantly 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 character­istics. THD+Noise is below 0.0004% throughout the audio
frequency range, 20Hz to 20kHz, with a 2kΩ load. In
addition, distortion remains relatively flat through its
wide output voltage swing range, providing increased head­room compared to other audio amplifiers, including the
OP176/275.

FIGURE 1. OPA134 Offset Voltage Trim Circuit.

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 voltage
level to a standard output level (1mW into 600Ω, or

0.7746Vrms). 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

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 mea­surements.

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 mea­surement 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 2kΩ, the impedance
seen by the positive and negative inputs in noninverting
applications should be matched. The p-channel JFETs in 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 since the
inverting input is held at virtual ground. However, in
noninverting applications the inputs do vary, and the gate­to-source voltage is not constant. The effect is increased
distortion due to the varying capacitance for unmatched
source impedances greater than 2kΩ.

To maintain low distortion, match unbalanced source im­pedance 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 R

and R2 is greater than 2kΩ, a

1

matching impedance on the noninverting input should be
used. As always, resistor values should be minimized to
reduce the effects of thermal noise.

NOISE PERFORMANCE

Circuit noise is determined by the thermal noise of external
resistors and op amp noise. Op amp noise is described by
two parameters—noise 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 perfor­mance. 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 imped­ances, refer to the typical curve, “Voltage Noise vs Source
Resistance.” Above 2kΩ source resistance, the op amp
contributes little additional noise—the voltage and current
terms in the total noise equation become insignificant and
the source resistance term dominates. Below 2kΩ, op amp
voltage noise dominates over the resistor noise, but com­pares 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-fol­lower 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 600Ω loads
with power supply voltage up to ±18V. Internal power
dissipation is increased when operating at high supply
voltages. Copper leadframe construction used in OPA134
series op amps improves heat dissipation compared to con­ventional 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 approxi­mately ±40mA at 25°C. The limit current decreases with
increasing temperature as shown in the typical performance
curve “Short-Circuit Current vs Temperature.”
