OP279GSZ from Analog Devices, 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	OUT A	output	Amplifier A output, rail-to-rail, sinks and sources about ±60 mA typical and is stable with capacitive loads to 10 nF.
2	-IN A	input	Amplifier A inverting input; differential input voltage is limited to ±1 V by back-to-back clamp diodes (limit input current to 5 mA beyond that).
3	+IN A	input	Amplifier A non-inverting input with rail-to-rail input range; differential input voltage is limited to ±1 V.
4	V-	power_in	Negative supply, or ground in single-supply operation; total supply voltage 4.5 V to 12 V (16 V absolute maximum).
5	+IN B	input	Amplifier B non-inverting input with rail-to-rail input range; differential input voltage is limited to ±1 V.
6	-IN B	input	Amplifier B inverting input; differential input voltage is limited to ±1 V by back-to-back clamp diodes (limit input current to 5 mA beyond that).
7	OUT B	output	Amplifier B output, rail-to-rail, sinks and sources about ±60 mA typical and is stable with capacitive loads to 10 nF.
8	V+	power_in	Positive supply; operation guaranteed from 4.5 V up to 12 V (16 V absolute maximum), under 3.5 mA supply current per amplifier.
