MCP6021-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	NC	unconnected	No internal connection; this pin is not connected inside the device.
2	VIN-	power_in	Inverting input of the operational amplifier, a high-impedance CMOS input with low bias current.
3	VIN+	power_in	Non-inverting input of the operational amplifier, a high-impedance CMOS input with low bias current.
4	VSS	power_in	Negative power supply pin; in typical single-supply use it is connected to ground and the other pins must stay between VSS and VDD.
5	VREF	power_in	Mid-supply reference voltage from an unbuffered internal resistor divider, available on the MCP6021 in this package.
6	VOUT	output	Analog output of the operational amplifier, a low-impedance voltage source.
7	VDD	power_in	Positive power supply pin, 2.5V to 5.5V above VSS, which requires a bypass capacitor.
8	NC	unconnected	No internal connection; this pin is not connected inside the device.
