PIN FUNCTION
No connect; grounded for best AC performance
Circuit1 Feedback from non-inverting output
Circuit 1 Non-inverting input
Circuit 4 Ground
Circuit 1
Reference input, sets common-mode output voltage with AV = 1. Must be st to
V+/2 for single supply applications
Circuit 4 Negative supply. Must be connected to GND for single supply operation
Circuit 2
Enable pin with internal pull-down; Logic “1” selects the disabled state; Logic “0”
selects the enabled state
Circuit 1 Inverting input
Circuit 1 Feedback from inverting output
Circuit 3 Inverting output
Circuit 4 Positive supply
Circuit 3 Non-inverting output
Circuit 5
Pack thermal pad electrically connected to IC substrate - must be connected to
most negative voltage applied to the IC
