MC33079DR2G from onsemi, in a SOIC-14. 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	OUT1	output	Output of op-amp channel 1. Low-impedance push-pull output; typical short-circuit current ±30 mA.
2	IN1-	input	Inverting input of op-amp channel 1. High-impedance bipolar input; typical input bias current 300 nA.
3	IN1+	input	Non-inverting input of op-amp channel 1. High-impedance bipolar input; common-mode range extends to within ~1.8 V of each supply rail.
4	VCC	power_in	Positive supply rail. Operating range ±2.5 V to ±18 V (5 V to 36 V single-supply). Typical quiescent current 4 mA per amplifier.
5	IN2+	input	Non-inverting input of op-amp channel 2. High-impedance bipolar input.
6	IN2-	input	Inverting input of op-amp channel 2. High-impedance bipolar input.
7	OUT2	output	Output of op-amp channel 2. Low-impedance push-pull output.
8	OUT3	output	Output of op-amp channel 3. Low-impedance push-pull output.
9	IN3-	input	Inverting input of op-amp channel 3. High-impedance bipolar input.
10	IN3+	input	Non-inverting input of op-amp channel 3. High-impedance bipolar input.
11	VEE	power_in	Negative supply rail (or GND in single-supply operation). Operating range ±2.5 V to ±18 V split, or 0 V for single-supply 5 V to 36 V use.
12	IN4+	input	Non-inverting input of op-amp channel 4. High-impedance bipolar input.
13	IN4-	input	Inverting input of op-amp channel 4. High-impedance bipolar input.
14	OUT4	output	Output of op-amp channel 4. Low-impedance push-pull output.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33079dr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc33079dr2g-etched.step`	2.9 MB	You want the part with `MC33079DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 699 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
