MAX9939 amplifier equivalent, spi programmable-gain amplifier.
programmable differential gains from 0.2V/V to 157V/V, input offset-voltage compensation, and an output amplifier that can be configured either as a high-order active fil.
It features programmable differential gains from 0.2V/V to 157V/V, input offset-voltage compensation, and an output amp.
The MAX9939 is a general-purpose, differential-input programmable-gain amplifier (PGA) that is ideal for conditioning a variety of wide dynamic range signals such as those found in motor current-sense, medical instrumentation, and sonar data acquisit.
