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 200
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 \x9640°C to +85°C temperature range.
