Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output, rail-to-rail swing. |
| 2 | INA- | input | Amplifier A inverting input, rail-to-rail with common-mode range from VSS-0.1V to VDD+0.1V. |
| 3 | INA+ | input | Amplifier A non-inverting input, rail-to-rail with common-mode range from VSS-0.1V to VDD+0.1V. |
| 4 | VSS | power_in | Negative supply or ground; for dual-supply operation, bypass with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Amplifier B non-inverting input, rail-to-rail with common-mode range from VSS-0.1V to VDD+0.1V. |
| 6 | INB- | input | Amplifier B inverting input, rail-to-rail with common-mode range from VSS-0.1V to VDD+0.1V. |
| 7 | OUTB | output | Amplifier B output, rail-to-rail swing. |
| 8 | VDD | power_in | Positive supply, 1.8V to 5.5V single supply (absolute max 7.5V VDD to VSS); place a 0.1µF ceramic capacitor close to the pin. |
