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.
