THEORY OF OPERATION The AD622 is a monolithic instrumentation amplifier based on a modification of the classic three op amp approach. Absolute value trimming allows the user to program gain accurately (to 0. 100) with only one ...

AD622 The AD622 provides greater accuracy at lower cost. The higher cost of the homebrew circuit is dominated in this case by the matched resistor network. One could also realize a homebrew design using cheaper discrete resistors that are either ...

GAIN SELECTION The AD622 gain is resistor programmed by R precisely, by whatever impedance appears between Pin 1 and Pin 8. The AD622 is designed to offer gains as close as possible to popular integer values using standard 1% resistors. ...
