## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output voltage for channel A with rail-to-rail voltage swing capability. |
| 2 | -IN A | input | Inverting input for channel A; input voltage (V-) - 0.5 V to (V+) + 0.5 V with maximum differential input ±1 V. |
| 3 | +IN A | input | Noninverting input for channel A; input voltage (V-) - 0.5 V to (V+) + 0.5 V with maximum differential input ±1 V. |
| 4 | V- | power_in | Negative (lowest) power supply; operating voltage range ±2.25 V to ±18 V with maximum supply voltage 40 V. |
| 5 | +IN B | input | Noninverting input for channel B; input voltage (V-) - 0.5 V to (V+) + 0.5 V with maximum differential input ±1 V. |
| 6 | -IN B | input | Inverting input for channel B; input voltage (V-) - 0.5 V to (V+) + 0.5 V with maximum differential input ±1 V. |
| 7 | OUT B | output | Output voltage for channel B with rail-to-rail voltage swing capability. |
| 8 | V+ | power_in | Positive (highest) power supply; operating voltage range ±2.25 V to ±18 V with maximum supply voltage 40 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
