DESCRIPTION

The INA103 is a very low noise, low distortion mono-

lithic instrumentation amplifier. Its current-feedback

circuitry achieves very wide bandwidth and excellent

dynamic response. It is ideal for low-level audio

signals such as balanced low-impedance microphones.

The INA103 provides near-theoretical limit noise per-

formance for 200

trial applications also benefit from its low noise and

wide bandwidth.

Unique distortion cancellation circuitry reduces dis-

tortion to extremely low levels, even in high gain. Its

balanced input, low noise and low distortion provide

superior performance compared to transformer-coupled

microphone amplifiers used in professional audio

equipment.

The INA103’s wide supply voltage ( 9 to 25V) and

high output current drive allow its use in high-level

audio stages as well. A copper lead frame in the plastic

DIP assures excellent thermal performance.
