Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier A, whose voltage range extends to within millivolts of each supply rail. |
| 2 | -IN1 | input | Inverting input of amplifier 1, with a voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 3 | +IN1 | input | Non-inverting input of amplifier 1, with the same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 4 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass it with a 0.1µF capacitor placed as close to the part as possible. |
| 5 | +IN2 | input | Non-inverting input of amplifier 2, with the same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 6 | -IN2 | input | Inverting input of amplifier 2, with a voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 7 | OUTB | output | Output of amplifier B, whose voltage range extends to within millivolts of each supply rail. |
| 8 | +Vs | power_in | Positive power supply (1.8V to 5.5V single supply); place a 0.1µF bypass capacitor as close to the part as possible. |
