MCP6231-E

Microchip Tech · Operational Amplifier · SOIC-8

MCP6231-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; leave unconnected.
2 VIN- power_in Inverting input is a high-impedance CMOS input with low bias current.
3 VIN+ power_in Noninverting input is a high-impedance CMOS input with low bias current; the common-mode input range extends from VDD + 300 mV to VSS - 300 mV.
4 VSS power_in Negative power supply; in single-supply operation it is connected to ground, and VDD must be 1.8V to 6.0V higher than VSS.
5 NC unconnected No internal connection; leave unconnected.
6 VOUT output Analog output is a low-impedance voltage source.
7 VDD power_in Positive power supply, 1.8V to 6.0V higher than VSS, requires bypass capacitors.
8 NC unconnected No internal connection; leave unconnected.
