Sensor Amplifier 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-impedance signal sources.

Features

1. Battery charge/discharge current detection

(for laptops, word processors, etc)

2. Signal amplifiers for magnetic sensors, pressure sensors, strain gauges

3. Instrumentation amps

4. Broad input range
