## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Rail-to-rail output of channel A with continuous short-circuit withstand capability |
| 2 | -IN A | input | Inverting input of channel A, common-mode range (V−)−0.5V to (V+)+0.5V with ±10mA maximum input current |
| 3 | +IN A | input | Noninverting input of channel A, common-mode range (V−)−0.5V to (V+)+0.5V with ±10mA maximum input current |
| 4 | V- | power_in | Negative (lowest) power supply, 0V in single-supply mode (4.5V to 36V) or −2.25V to −18V in dual-supply mode |
| 5 | +IN B | input | Noninverting input of channel B, common-mode range (V−)−0.5V to (V+)+0.5V with ±10mA maximum input current |
| 6 | -IN B | input | Inverting input of channel B, common-mode range (V−)−0.5V to (V+)+0.5V with ±10mA maximum input current |
| 7 | OUT B | output | Rail-to-rail output of channel B with continuous short-circuit withstand capability |
| 8 | V+ | power_in | Positive (highest) power supply, 4.5V to 36V in single-supply mode or +2.25V to +18V in dual-supply mode |
