DESCRIPTION
The OPA2604 is a dual, FET-input operational ampli-
fier 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 low-noise FET input of the
OPA2604 provides wide dynamic range, even with high
source impedance. Offset voltage is laser-trimmed to
minimize the need for interstage coupling capacitors.
The OPA2604 is available in 8-pin plastic mini-DIP
and SO-8 surface-mount packages, specified for the
–25°C to +85°C temperature range.

DISCHARGE SENSITIVITY
Any integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate 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 speci-
fications.

APPLICATIONS INFORMATION
The OPA2604 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 ca-
pacitors close to the device pins. In most cases 1µF tantalum
capacitors are adequate.
DISTORTION MEASUREMENTS
The distortion produced by the OPA2604 is below the mea-
surement limit of virtually all commercially available equip-
ment. A special test circuit, however, 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 1 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. 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 measure-
ment instruments.
CAPACITIVE LOADS
The dynamic characteristics of the OPA2604 have been
optimized for commonly encountered gains, loads and oper-
ating 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 2 shows various
circuits which preserve phase margin with capacitive load.
Request Application Bulletin AB-028 for details of analysis
techniques and applications circuits.
For the unity-gain buffer, Figure 2a, 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 2b, does not limit the output with low
load impedance. It provides a small amount of positive feed-
back 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 2c and 2d show compensation techniques for
noninverting amplifiers. Like the follower circuits, the circuit
in Figure 2d eliminates voltage drop due to load current, but
at the penalty of somewhat reduced input impedance at high
frequency.
Figures 2e and 2f 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 bipolar-input op amps
react with the source impedance and will dominate. At a few
thousand ohms source impedance and above, the OPA2604
will generally provide lower noise.

Copper leadframe construction used in the OPA2604 im-
proves 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 approxi-
mately ±40mA at 25°C. The limit current decreases with
increasing temperature as shown in the typical curves.

POWER DISSIPATION
The OPA2604 is capable of driving 600Ω loads with power
supply voltages up to ±24V. Internal power dissipation is
increased when operating at high power supply voltage. The
typical performance curve, Power Dissipation vs Power Sup-
ply 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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
