Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUTA | output | Analog output of op amp A, a low-impedance voltage source. |
| 2 | VINA- | input | Inverting input of op amp A, a high-impedance CMOS input with low bias current. |
| 3 | VINA+ | input | Non-inverting input of op amp A, a high-impedance CMOS input with low bias current. |
| 4 | VSS | power_in | Negative power supply, connected to ground in typical single-supply operation, with VDD 1.8V to 5.5V above it. |
| 5 | VINB+ | input | Non-inverting input of op amp B, a high-impedance CMOS input with low bias current. |
| 6 | VINB- | input | Inverting input of op amp B, a high-impedance CMOS input with low bias current. |
| 7 | VOUTB | output | Analog output of op amp B, a low-impedance voltage source. |
| 8 | VDD | power_in | Positive power supply, 1.8V to 5.5V higher than VSS, requiring bypass capacitors. |
