MM1089, Sensor Amplifier

MITSUMI Sensor Amplifier MM1089 Sensor Amplifier Monolithic IC MM1089 Outline This IC is an amplifier with a high-impedance differential input, which can be used in high-CMR instrumentation.

Particularly when amplifying signals from a high-impedance or high-bias signal source, often signals are buried in noise, making amplification difficult.

This IC amplifies only the signal, and the noise is suppressed rather than amplified, making it effective for use where noise is prominent or with high-
