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