DESCRIPTION
The INA163 is a very low-noise, low-distortion, mon-
olithic instrumentation amplifier. Its current-feedback
circuitry achieves very wide bandwidth and excellent
dynamic response over a wide range of gain. It is ideal
for low-level audio signals such as balanced low-
impedance microphones. Many industrial, instrumen-
tation, and medical applications also benefit from its
low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces distor-
tion to extremely low levels, even in high gain. The
INA163 provides near-theoretical noise performance
for 200source impedance. Its differential input, low
noise, and low distortion provide superior performance
in professional microphone amplifier applications.
The INA163’s wide supply voltage, excellent output
voltage swing, and high output current drive allow its
use in high-level audio stages as well.
The INA163 is available in a space-saving SO-14
surface-mount package, specified for operation over
the –40°C to +85°C temperature range.

APPLICATIONS INFORMATION
Figure 1 shows the basic connections required for
operation. Power supplies should be bypassed with
0.1µF tantalum capacitors near the device pins. The
output Sense (pin 8) and output Reference (pin 10)
should be low-impedance connections. Resistance of
a few ohms in series with these connections will
degrade the common-mode rejection of the INA163.
GAIN-SET RESISTOR
Gain is set with an external resistor, RG, as shown in
Figure 1. The two internal 3kfeedback resistors are
laser-trimmed to 3kwithin approximately ±0.2%. Gain
is:
G = 1+ 6000
RG
The temperature coefficient of the internal 3kresis-
tors is approximately ±25ppm/°C. Accuracy and TCR
of the external RG will also contribute to gain error and
temperature drift. These effects can be inferred from
the gain equation. Make a short, direct connection to
the gain set resistor, RG. Avoid running output signals
near these sensitive input nodes.
NOISE PERFORMANCE
The INA163 provides very low-noise with low-source
impedance. Its 1nV/Hz voltage noise delivers near-
theoretical noise performance with a source imped-
ance of 200. The input stage design used to achieve
this low noise, results in relatively high input bias
current and input bias current noise. As a result, the
INA163 may not provide the best noise performance
with a source impedance greater than 10k. For source
impedance greater than 10k, other instrumentation
amplifiers may provide improved noise performance.
