DESCRIPTION
Inverting amplifier input
Common-mode voltage input
Amplifier positive power-supply input
Noninverting amplifier output
Inverting amplifier output
Amplifier negative power-supply input. Note that V_S– is tied together on multi-channel devices.
Power down. PD = logic low puts device into low-power mode. PD = logic high or open for normal
operation.
Noninverting amplifier input
