## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Channel A amplifier output, which swings rail-to-rail and can source and sink 11mA with a +5V supply. |
| 2 | INA- | input | Channel A inverting amplifier input. |
| 3 | INA+ | input | Channel A noninverting amplifier input; the common-mode input range extends down to VSS (ground sensing). |

| 5 | INB+ | input | Channel B noninverting amplifier input. |
| 6 | INB- | input | Channel B inverting amplifier input. |
| 7 | OUTB | output | Channel B amplifier output, which swings rail-to-rail. |
| 8 | OUTC | output | Channel C amplifier output, which swings rail-to-rail. |
| 9 | INC- | input | Channel C inverting amplifier input. |
| 10 | INC+ | input | Channel C noninverting amplifier input. |
| 11 | VSS | power_in | Negative power-supply voltage (ground reference for the single supply); the input common-mode range extends down to VSS. |
| 12 | IND+ | input | Channel D noninverting amplifier input. |
| 13 | IND- | input | Channel D inverting amplifier input. |
| 14 | OUTD | output | Channel D amplifier output, which swings rail-to-rail. |
