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 200Ω source 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.
