A222 Selectable Gain Amplifier

The A222 is a non-inverting operational amplifier featuring high input impedance. It utilizes a precision voltage divider and an A124 Analog Multiplexer to allow for computer-controlled gain selection (1, 2, 4, or 8) within the AD15 Analog Subsystem. The module includes defined input pins for feedback and signal, as well as specific power requirements of ±15V.
