INA 166

Low-Noise, Low-Distortion, G = 2000 INSTRUMENTATION AMPLIFIER
FEATURES
q q q q q q q LOW NOISE: 1.3nV/√Hz at 1kHz LOW THD+N: 0.09% at 1kHz WIDE BANDWIDTH: 450kHz WIDE SUPPLY RANGE: ±4.5V to ±18V HIGH CMR: > 100dB GAIN SET WITH EXTERNAL RESISTOR SO-14 SURFACE-MOUNT PACKAGE
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.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less.

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.
