## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output pin of channel A that provides rail-to-rail output with ±65 mA maximum output current. |
| 2 | -IN A | input | Inverting input pin of channel A that accepts common-mode input voltages from (V-) - 0.5 V to (V+) + 0.5 V. |
| 3 | +IN A | input | Noninverting input pin of channel A that accepts common-mode input voltages from (V-) - 0.5 V to (V+) + 0.5 V. |
| 4 | V- | power_in | Negative power supply pin that operates at voltages from ±2.25 V to ±18 V (dual supply) or 4.5 V to 36 V (single supply). |
| 5 | +IN B | input | Noninverting input pin of channel B that accepts common-mode input voltages from (V-) - 0.5 V to (V+) + 0.5 V. |
| 6 | -IN B | input | Inverting input pin of channel B that accepts common-mode input voltages from (V-) - 0.5 V to (V+) + 0.5 V. |
| 7 | OUT B | output | Output pin of channel B that provides rail-to-rail output with ±65 mA maximum output current. |
| 8 | V+ | power_in | Positive power supply pin that operates at voltages from ±2.25 V to ±18 V (dual supply) or 4.5 V to 36 V (single supply). |
