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-impedance signal sources.
