MCP6477T-E from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
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 currents. |
| 3 | VINA+ | input | Noninverting input of op amp A, a high-impedance CMOS input with low bias currents. |
| 4 | VSS | power_in | Negative power supply; typically connected to ground in single-supply operation, with VDD 1.8V to 5.5V higher than VSS. |
| 5 | VINB+ | input | Noninverting input of op amp B, a high-impedance CMOS input with low bias currents. |
| 6 | VINB- | input | Inverting input of op amp B, a high-impedance CMOS input with low bias currents. |
| 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; the datasheet states VDD needs bypass capacitors. |
