## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Amplifier 1 output; the output voltage range extends to within millivolts of each supply rail. |
| 2 | -IN1 | input | Amplifier 1 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 3 | +IN1 | input | Amplifier 1 non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 4 | +Vs | power_in | Positive power supply (2.5V to 5.5V); place a 0.1μF bypass capacitor as close to the part as possible. |
| 5 | +IN2 | input | Amplifier 2 non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 6 | -IN2 | input | Amplifier 2 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 7 | OUT2 | output | Amplifier 2 output; the output voltage range extends to within millivolts of each supply rail. |
| 8 | OUT3 | output | Amplifier 3 output; the output voltage range extends to within millivolts of each supply rail. |
| 9 | -IN3 | input | Amplifier 3 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 10 | +IN3 | input | Amplifier 3 non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 11 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass with a 0.1μF capacitor close to the part. |
| 12 | +IN4 | input | Amplifier 4 non-inverting input; same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 13 | -IN4 | input | Amplifier 4 inverting input; voltage range can go from -Vs -0.3V to +Vs + 0.3V. |
| 14 | OUT4 | output | Amplifier 4 output; the output voltage range extends to within millivolts of each supply rail. |
