## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Out1 | output | Channel 1 rail-to-rail output, typically sinking 32 mA and sourcing 35 mA, and stable with capacitive loads up to 100 pF in a follower. |
| 2 | In1- | input | Channel 1 inverting input, with input voltage limited to (VCC-) - 0.2 V to (VCC+) + 0.2 V and input current limited to 10 mA by a series resistor. |
| 3 | In1+ | input | Channel 1 non-inverting input, with common-mode range of (VCC-) - 0.1 V to (VCC+) + 0.1 V and about 1 pA typical bias current. |
| 4 | VCC- | power_in | Negative supply voltage, or ground in single-supply use, with the total supply range 2.5 V to 5.5 V (absolute maximum 6 V). |
| 5 | In2+ | input | Channel 2 non-inverting input, with common-mode range of (VCC-) - 0.1 V to (VCC+) + 0.1 V and about 1 pA typical bias current. |
| 6 | In2- | input | Channel 2 inverting input, with input voltage limited to (VCC-) - 0.2 V to (VCC+) + 0.2 V and input current limited to 10 mA by a series resistor. |
| 7 | Out2 | output | Channel 2 rail-to-rail output, typically sinking 32 mA and sourcing 35 mA, and stable with capacitive loads up to 100 pF in a follower. |
| 8 | VCC+ | power_in | Positive supply voltage, 2.5 V to 5.5 V over -40 to 125 °C (absolute maximum 6 V), with a 10 nF decoupling capacitor advised close to the pin. |
