MCP6422-E

Microchip Tech · Operational Amplifier · MSOP-8

MCP6422-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 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.
