MC34072VDR2G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Output 1	output	Op-amp 1 output. All-NPN output stage with symmetrical source/sink current (typ 30 mA), drives 0 to 10,000 pF capacitive loads. Output swing 13.4 V to -14.7 V with +-15 V supplies into 2 kOhm.
2	Inputs 1 (-)	input	Op-amp 1 inverting input. Darlington PNP input stage; input bias current typ 100 nA, differential input resistance typ 150 MOhm, input offset voltage 1.0 mV typ / 5.0 mV max (non-A suffix).
3	Inputs 1 (+)	input	Op-amp 1 non-inverting input. Common-mode input range extends from VEE to (VCC - 1.8 V), enabling true single-supply operation with ground-referenced signals.
4	VEE	power_in	Negative supply / ground rail. Tie to GND for single-supply operation (3.0 V to 44 V total supply) or to a negative rail for split-supply use with
5	Inputs 2 (+)	input	Op-amp 2 non-inverting input. Common-mode input range extends from VEE to (VCC - 1.8 V).
6	Inputs 2 (-)	input	Op-amp 2 inverting input. Darlington PNP input stage; input bias current typ 100 nA.
7	Output 2	output	Op-amp 2 output. All-NPN output stage, output short-circuit current typ 30 mA source and sink, indefinite short-circuit duration.
8	VCC	power_in	Positive supply rail. 3.0 V to 44 V single-supply, or +-22 V split. Quiescent current per amplifier is typ 1.9 mA (2.5 mA max) at +-15 V.
