2 −IN A input Inverting input, channel A; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
3 +IN A input Noninverting input, channel A; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
4 V+ power_in Positive (highest) power supply; supply voltage range ±2.25 V to ±18 V or 4.5 V to 36 V.
5 +IN B input Noninverting input, channel B; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
6 −IN B input Inverting input, channel B; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
7 OUT B output Output, channel B; output voltage swing from (V-) + 0.8 V to (V+) - 0.8 V.
8 OUT C output Output, channel C; output voltage swing from (V-) + 0.8 V to (V+) - 0.8 V.
9 −IN C input Inverting input, channel C; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
10 +IN C input Noninverting input, channel C; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
11 V− power_in Negative (lowest) power supply; supply voltage range ±2.25 V to ±18 V or 4.5 V to 36 V.
12 +IN D input Noninverting input, channel D; common-mode voltage range (V-) + 0.5 V to (V+) - 2 V.
