Low-Noise, Low-Distortion, G = 2000

INSTRUMENTATION AMPLIFIER

FEATURES

● 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

APPLICATIONS

● MOVING-COIL TRANSDUCER AMPLIFIERS

● DIFFERENTIAL RECEIVERS

● BRIDGE TRANSDUCER AMPLIFIERS

●●MICROPHONE AND HYDROPHONE

PREAMPS

● GAIN SET WITH EXTERNAL RESISTOR

● SO-14 SURFACE-MOUNT PACKAGE

Unique distortion cancellation circuitry reduces dis-

tortion to extremely low levels, even in high gain.

The INA166 provides near-theoretical noise perfor-

mance for 200Ω source impedance. Its differential

input, low noise, and low distortion provide superior

performance as a low-level signal amplifier.

DESCRIPTION

The INA166 is a very low-noise, low-distortion, mon-

olithic 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 hydro-

phones. Many industrial, instrumentation, and medical

applications also benefit from its low noise and wide

bandwidth.

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.
