## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Out1 | output | Output of amplifier 1, which swings rail-to-rail; the datasheet notes a maximum output current of approximately 48 mA independent of VCC, and short-circuits to VCC can cause excessive heating. |
| 2 | In1- | input | Inverting input of amplifier 1; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 3 | In1+ | input | Non-inverting input of amplifier 1; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 4 | VCC+ | power_in | Positive supply voltage, specified from 1.8 V to 6 V operating, with an absolute maximum of 7 V. |
| 5 | In2+ | input | Non-inverting input of amplifier 2; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 6 | In2- | input | Inverting input of amplifier 2; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 7 | Out2 | output | Output of amplifier 2, which swings rail-to-rail; the datasheet notes a maximum output current of approximately 48 mA independent of VCC, and short-circuits to VCC can cause excessive heating. |
| 8 | Out3 | output | Output of amplifier 3, which swings rail-to-rail; the datasheet notes a maximum output current of approximately 48 mA independent of VCC, and short-circuits to VCC can cause excessive heating. |
| 9 | In3- | input | Inverting input of amplifier 3; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 10 | In3+ | input | Non-inverting input of amplifier 3; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 11 | VCC- | power_in | Negative supply rail, which is 0 V in the datasheet's electrical characteristics test conditions. |
| 12 | In4+ | input | Non-inverting input of amplifier 4; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 13 | In4- | input | Inverting input of amplifier 4; the common-mode input range extends from VCC- - 0.2 V to VCC+ + 0.2 V, and the input voltage must stay within VCC- - 0.3 V to VCC+ + 0.3 V. |
| 14 | Out4 | output | Output of amplifier 4, which swings rail-to-rail; the datasheet notes a maximum output current of approximately 48 mA independent of VCC, and short-circuits to VCC can cause excessive heating. |
