MCP6051-E

Microchip Tech · Operational Amplifier · SOIC-8

MCP6051-E from Microchip Tech, in a SOIC-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 NC unconnected No Internal Connection; the pin has no internal connection on the MCP6051 SOIC package.
2 VIN- power_in Inverting input of the op amp, a high-impedance CMOS input with low bias current.
3 VIN+ power_in Non-inverting input of the op amp, a high-impedance CMOS input with low bias current.
4 VSS power_in Negative power supply; VDD must be 1.8V to 6.0V higher than VSS, and VSS is tied to ground in single-supply use.
5 NC unconnected No Internal Connection; the pin has no internal connection on the MCP6051 SOIC package.
6 VOUT output Analog output, a low-impedance voltage source.
7 VDD power_in Positive power supply, 1.8V to 6.0V higher than VSS, which requires bypass capacitors.
8 NC unconnected No Internal Connection; the pin has no internal connection on the MCP6051 SOIC package.
