MCP616-I from Microchip Tech, in a PDIP-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 on the MCP616 PDIP-8 package (pin 1 is NC).
2	VIN-	power_in	Inverting input of the op amp, a high-impedance PNP input with low bias current.
3	VIN+	power_in	Non-inverting input of the op amp, a high-impedance PNP input with low bias current.
4	VSS	power_in	Negative power supply; in single-supply operation VSS is connected to ground, and the other pins must stay between VSS and VDD for normal operation.
5	NC	unconnected	No internal connection on the MCP616 PDIP-8 package (pin 5 is NC).
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, which needs bypass capacitors.
8	NC	unconnected	No internal connection on the MCP616 PDIP-8 package (pin 8 is NC).
