Low-Noise Low-Distortion Instrumentation Amplifier - INA163

INA163 (ACTIVE)

Low-Noise Low-Distortion Instrumentation Amplifier

 

Description

The INA163 is a very low-noise, low-distortion, monolithic 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, instrumentation, and medical applications also benefit from its low noise and wide bandwidth.

Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. The INA163 provides near-theoretical noise performance for 200 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.
