MCP6V28-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.
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, typically connected to ground in single-supply use.
5	NC	unconnected	No internal connection.
6	VOUT	output	Op amp output, a low-impedance voltage source.
7	VDD	power_in	Positive power supply, 2.3V to 5.5V above VSS, and needs bypass capacitors.
8	CS	input	Chip Select, a CMOS Schmitt-triggered digital input that places the MCP6V28 into a low power mode.
