DESCRIPTION
The INA137 and INA2137 are differential line receivers
consisting of high performance op amps with on-chip
precision resistors. They are fully specified for high
performance audio applications and have excellent ac
specifications, including low distortion (0.0005% at
1kHz) and high slew rate (14V/µs), assuring good
dynamic response. In addition, wide output voltage
swing and high output drive capability allow use in a
wide variety of demanding applications. The dual ver-
sion features completely independent circuitry for low-
est crosstalk and freedom from interaction, even when
overdriven or overloaded.
The INA137 and INA2137 on-chip resistors are laser
trimmed for accurate gain and optimum
common-mode rejection. Furthermore, excellent TCR
tracking of the resistors maintains gain accuracy and
common-mode rejection over temperature. Operation
is guaranteed from ±4V to ±18V (8V to 36V total
supply).
The INA137 is available in 8-pin DIP and SO-8
surface-mount packages. The INA2137 comes in
14-pin DIP and SO-14 surface-mount packages. Both
are specified for operation over the extended industrial
temperature range, –40°C to +85°C.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This 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 its published
specifications.

INA137, INA2137
The INA137 and INA2137 have excellent distortion charac-
teristics. THD+Noise is below 0.001% throughout the audio
frequency range. Up to approximately 10kHz distortion is
below the measurement limit of commonly used test equip-
ment. Furthermore, distortion remains relatively flat over its
wide output voltage swing range (approximately 1.7V from
either supply).
OFFSET VOLTAGE TRIM
The INA137 and INA2137 are laser trimmed for low offset
voltage and drift. Most applications require no external offset
adjustment. Figure 3 shows an optional circuit for trimming
the output offset voltage. The output is referred to the output
reference terminal (pin 1), which is normally grounded. A
voltage applied to the Ref terminal will be summed with the
output signal. This can be used to null offset voltage as
shown in Figure 3. The source impedance of a signal applied
to the Ref terminal should be less than 10Ω to maintain good
common-mode rejection.
APPLICATIONS INFORMATION
The INA137 and INA2137 are differential line receivers
suitable for a wide range of audio and general-purpose
applications. Figure 1 shows the basic G = 1/2 (–6dB)
differential receiver configuration. The input and feedback
resistors can be reversed to achieve G = 2 (+6dB), as shown
in Figure 2. For applications requiring G = 1 (0dB), the
INA134 and INA2134 are recommended.
Decoupling capacitors are strongly recommended for appli-
cations with noisy or high impedance power supplies. The
capacitors should be placed close to the device pins as
shown in Figure 1. All circuitry is completely independent
in the dual version assuring lowest crosstalk and normal
behavior when one amplifier is overdriven or short-cir-
cuited.
As shown in Figure 1, the differential input signal is con-
nected to pins 2 and 3. The source impedances connected to
the inputs must be nearly equal to assure good common-
mode rejection. A 5Ω mismatch in source impedance will
degrade the common-mode rejection of a typical device to
approximately 77dB (RTO). If the source has a known
impedance mismatch, an additional resistor in series with
the opposite input can be used to preserve good common-
mode rejection.
FIGURE 3. Offset Adjustment.
AUDIO PERFORMANCE
The INA137 and INA2137 were designed for enhanced ac
performance. Very low distortion, low noise, and wide band-
width provide superior performance in high quality audio
applications. Laser-trimmed matched resistors provide opti-
mum common-mode rejection (typically 90dB), especially
when compared to circuits implemented with an op amp
and discrete precision resistors. In addition, high slew rate
(14V/µs) and fast settling time (3µs to 0.01%) ensure excel-
lent dynamic performance.
