VIN- 2 I Negative (inverting) input
VIN+ 3 I Positive (non-inverting) input
VS− 4 − Negative supply
RG 5 I Gain setting input. Place a resistor network between pin 1 and pin 5.
VO 6 O Output of amplifier A2
VS+ 7 − Positive supply
VO1 8 O Output of amplifier A1
(1) Signal Types: I = Input, O = Output, I/O = Input or Output.
