## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output; output voltage range extends to within millivolts of each supply rail. |
| 2 | -INA | input | Amplifier A inverting input; voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 3 | +INA | input | Amplifier A non-inverting input; same voltage range as -IN. |
| 4 | +Vs | power_in | Positive power supply (1.8V to 5.5V); place a 0.1µF bypass capacitor as close to the part as possible. |
| 5 | +INB | input | Amplifier B non-inverting input; same voltage range as -IN. |
| 6 | -INB | input | Amplifier B inverting input; voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 7 | OUTB | output | Amplifier B output; output voltage range extends to within millivolts of each supply rail. |
| 8 | OUTC | output | Amplifier C output; output voltage range extends to within millivolts of each supply rail. |
| 9 | -INC | input | Amplifier C inverting input; voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 10 | +INC | input | Amplifier C non-inverting input; same voltage range as -IN. |
| 11 | -Vs | power_in | Negative power supply or ground; if not grounded, bypass with a 0.1µF capacitor close to the part. |
| 12 | +IND | input | Amplifier D non-inverting input; same voltage range as -IN. |
| 13 | -IND | input | Amplifier D inverting input; voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 14 | OUTD | output | Amplifier D output; output voltage range extends to within millivolts of each supply rail. |
