Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Open-drain output of channel A, with signal output limited to (V-)-0.3 V to (V+)+0.3 V and ±55 mA per the absolute maximum ratings. |
| 2 | -INA | input | Inverting input of channel A, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA. |
| 3 | +INA | input | Noninverting input of channel A, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA. |
| 4 | V- | power_in | Negative (lowest) power supply pin; single-supply operation is specified from 3 V to 36 V between V+ and V-. |
| 5 | +INB | input | Noninverting input of channel B, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA. |
