## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier A, rail-to-rail swing. |
| 2 | INA- | input | Inverting input of amplifier A, common-mode range VSS-0.1V to VDD+0.1V. |
| 3 | INA+ | input | Non-inverting input of amplifier A, common-mode range VSS-0.1V to VDD+0.1V. |
| 4 | VDD | power_in | Positive supply for 1.8V to 5.5V single-supply operation (absolute max 7.5V to VSS), bypassed with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Non-inverting input of amplifier B, common-mode range VSS-0.1V to VDD+0.1V. |
| 6 | INB- | input | Inverting input of amplifier B, common-mode range VSS-0.1V to VDD+0.1V. |
| 7 | OUTB | output | Output of amplifier B, rail-to-rail swing. |
| 8 | OUTC | output | Output of amplifier C, rail-to-rail swing. |
| 9 | INC- | input | Inverting input of amplifier C, common-mode range VSS-0.1V to VDD+0.1V. |
| 10 | INC+ | input | Non-inverting input of amplifier C, common-mode range VSS-0.1V to VDD+0.1V. |
| 11 | VSS | power_in | Negative supply or ground reference for the amplifiers. |
| 12 | IND+ | input | Non-inverting input of amplifier D, common-mode range VSS-0.1V to VDD+0.1V. |
| 13 | IND- | input | Inverting input of amplifier D, common-mode range VSS-0.1V to VDD+0.1V. |
| 14 | OUTD | output | Output of amplifier D, rail-to-rail swing. |
