## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output, rail-to-rail swing with typical 53mA output current at 5V. |
| 2 | INA- | input | Amplifier A inverting input, common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). |
| 3 | INA+ | input | Amplifier A non-inverting input, common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). |
| 4 | VSS | power_in | Negative supply, ground in single-supply operation; dual supplies of ±1.05V to ±2.75V are supported. |
| 5 | INB+ | input | Amplifier B non-inverting input, common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). |
| 6 | INB- | input | Amplifier B inverting input, common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). |
| 7 | OUTB | output | Amplifier B output, rail-to-rail swing with typical 53mA output current at 5V. |
| 8 | VDD | power_in | Positive supply, 2.1V to 5.5V (absolute max 7.5V between VDD and VSS), bypass with 0.1µF ceramic capacitor close to the pin. |
