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.
APPLICATIONS q MOVING-COIL TRANSDUCER AMPLIFIERS q DIFFERENTIAL RECEIVERS q BRIDGE TRANSDUCER AMPLIFIERS q MICROPHONE AND HYDROPHONE
PREAMPS
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.
