MCP6142T-I 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	VOUTA	output	Analog output of op amp A, a low-impedance voltage source.
2	VINA-	input	Inverting input of op amp A, a high-impedance CMOS input with low bias current.
3	VINA+	input	Non-inverting input of op amp A, a high-impedance CMOS input with low bias current.
4	VSS	power_in	Negative power supply, connected to ground in a single-supply configuration.
5	VINB+	input	Non-inverting input of op amp B, a high-impedance CMOS input with low bias current.
6	VINB-	input	Inverting input of op amp B, a high-impedance CMOS input with low bias current.
7	VOUTB	output	Analog output of op amp B, a low-impedance voltage source.
8	VDD	power_in	Positive power supply, 1.4V to 6.0V higher than VSS, and it needs bypass capacitors.
