DESCRIPTION
The OPA604 is a FET-input operational amplifier designed
for enhanced AC performance. Very low distortion, low noise
and wide bandwidth provide superior performance in high
quality audio and other applications requiring excellent dynamic performance.
New circuit techniques and special laser trimming of dynamic
circuit performance yield very low harmonic distortion. The
result is an op amp with exceptional sound quality. The lownoise FET input of the OPA604 provides wide dynamic
range, even with high source impedance. Offset voltage is
laser-trimmed to minimize the need for interstage coupling
capacitors.
The OPA604 is available in 8-pin plastic mini-DIP and SO-8
surface-mount packages, specified for the –25°C to +85°C
temperature range.

Any integrated circuit can be damaged by ESD. Texas Instruments 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 published specifications.

APPLICATIONS INFORMATION
OFFSET VOLTAGE ADJUSTMENT
The OPA604 offset voltage is laser-trimmed and will require
no further trim for most applications. As with most amplifiers,
externally trimming the remaining offset can change drift
performance by about 0.3µV/°C for each 100µV of adjusted
offset. The OPA604 can replace many other amplifiers by
leaving the external null circuit unconnected.
The OPA604 is unity-gain stable, making it easy to use in a
wide range of circuitry. Applications with noisy or high impedance power supply lines may require decoupling capacitors
close to the device pins. In most cases, a 1µF tantalum
capacitor at each power supply pin is adequate.

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 noninverting 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. This
extends the measurement limit, including the effects of the
signal-source purity, by a factor of 101. Note that the input
signal and load applied to the op amp are the same as with
conventional feedback without R3.
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 the Audio Precision System One, which greatly simplifies such repetitive measurements. The measurement technique can, however, be performed with manual distortion
measurement instruments.

DISTORTION MEASUREMENTS
The distortion produced by the OPA604 is below the measurement limit of virtually all commercially available equipment. A special test circuit, however, can be used to extend
the measurement capabilities.
The dynamic characteristics of the OPA604 have been
optimized for commonly encountered gains, loads and operating conditions. The combination of low closed-loop gain
and capacitive load will decrease the phase margin and may
lead to gain peaking or oscillations. Load capacitance reacts
with the op amp’s open-loop output resistance to form an
additional pole in the feedback loop. Figure 3 shows various
circuits which preserve phase margin with capacitive load.
For details of analysis techniques and applications circuits,
refer to application bulletin AB-028 (SBOA015) located at

For the unity-gain buffer, Figure 3a, stability is preserved by
adding a phase-lead network, RC and CC. Voltage drop
across RC will reduce output voltage swing with heavy loads.
An alternate circuit, Figure 3b, does not limit the output with
low load impedance. It provides a small amount of positive
feedback to reduce the net feedback factor. Input impedance
of this circuit falls at high frequency as op amp gain rolloff
reduces the bootstrap action on the compensation network.
Figures 3c and 3d show compensation techniques for
noninverting amplifiers. Like the follower circuits, the circuit in
Figure 3d eliminates voltage drop due to load current, but at
the penalty of somewhat reduced input impedance at high
frequency.
Figures 3e and 3f show input lead compensation networks
for inverting and difference amplifier configurations.
NOISE PERFORMANCE
Op amp noise is described by two parameters—noise voltage and noise current. The voltage noise determines the
noise performance with low source impedance. Low noise
bipolar-input op amps such as the OPA27 and OPA37
provide very low voltage noise. But if source impedance is
greater than a few thousand ohms, the current noise of
R1
bipolar-input op amps react with the source impedance and
will dominate. At a few thousand ohms source impedance
and above, the OPA604 will generally provide lower noise.
POWER DISSIPATION
The OPA604 is capable of driving a 600Ω load with powersupply voltages up to ±24V. Internal power dissipation is
increased when operating at high power supply voltage. The
typical characteristic curve, Power Dissipation vs Power
Supply Voltage, shows quiescent dissipation (no signal or no
load) as well as dissipation with a worst case continuous sine
wave. Continuous high-level music signals typically produce
dissipation significantly less than worst-case sine waves.
Copper leadframe construction used in the OPA604 improves heat dissipation compared to conventional plastic
packages. To achieve best heat dissipation, solder the device directly to the circuit board and use wide circuit board
traces.
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 curves.

THE OPA604 DESIGN
The OPA604 uses FETs throughout the signal path,
including the input stage, input-stage load, and the
important phase-splitting section of the output stage.
Bipolar transistors are used where their attributes,
such as current capability are important, and where
their transfer characteristics have minimal impact.
The topology consists of a single folded-cascode gain
stage followed by a unity-gain output stage. Differential input transistors J1 and J2 are special large-geometry, P-channel JFETs. Input stage current is a relatively high 800µA, providing high transconductance
and reducing voltage noise. Laser trimming of stage
currents and careful attention to symmetry yields a
nearly symmetrical slew rate of ±25V/µs.
The drains of J1 and J2 are cascoded by Q1 and Q2,
driving the input stage loads, FETs J3 and J4. Distortion reduction circuitry (patented) linearizes the openloop response and increases voltage gain. The 20MHz
bandwidth of the OPA604 further reduces distortion
through the user-connected feedback loop.

The JFET input stage holds input bias current to
approximately 50pA or roughly 3000 times lower than
common bipolar-input audio op amps. This dramatically reduces noise with high-impedance circuitry.

SOUND QUALITY
Many audio experts believe that the sound quality of a
high performance FET op amp is superior to that of
bipolar op amps. A possible reason for this is that
bipolar designs generate greater odd-order harmonics
than FETs. To the human ear, odd-order harmonics
have long been identified as sounding more unpleasant than even-order harmonics. FETs, like vacuum
tubes, have a square-law I-V transfer function which is
more linear than the exponential transfer function of a
bipolar transistor. As a direct result of this square-law
characteristic, FETs produce predominantly even-order harmonics. Figure 10 shows the transfer function of
a bipolar transistor and FET. Fourier transformation of
both transfer functions reveals the lower odd-order
harmonics of the FET amplifier stage.

The sound quality of an op amp is often the crucial
selection criteria—even when a data sheet claims
exceptional distortion performance. By its nature, sound
quality is subjective. Furthermore, results of listening
tests can vary depending on application and circuit
configuration. Even experienced listeners in controlled
tests often reach different conclusions.

The output stage consists of a JFET phase-splitter
loaded into high speed all-NPN output drivers. Output
transistors are biased by a special circuit to prevent
cutoff, even with full output swing into 600Ω loads.
