DESCRIPTION

The INA166 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 signals such as microphones or hydrophones.

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 INA166 provides near-theoretical noise performance

for 200Ω source impedance. Its differential

input, low noise, and low distortion provide superior

performance as a low-level signal amplifier.

The INA166 is available in a space-saving SO-14

surface-mount package, specified for operation over

the –40°C to +85°C temperature range.
