INA103 - Low Noise/ Low Distortion INSTRUMENTATION AMPLIFIER

Download the INA103 datasheet PDF. This datasheet also covers the INA103_Burr variant, as both devices belong to the same low noise/ low distortion instrumentation amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The INA103 is a very low noise, low distortion monolithic 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.

Key Features

  • q LOW NOISE: 1nV/√Hz q LOW THD+N: 0.0009% at 1kHz, G = 100 q HIGH GBW: 100MHz at G = 1000 q WIDE SUPPLY RANGE: ±9V to ±25V q HIGH CMRR: >100dB q BUILT-IN GAIN.
