MC33078DR2G 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	OUT1	output	Output of amplifier 1. Class-AB bipolar output stage capable of ±14.1 V swing into 10 kΩ, source ~+29 mA / sink ~-37 mA short-circuit current at ±15 V supplies.
2	IN1-	input	Inverting input of amplifier 1. Typical input bias current 300 nA, input offset current 25 nA, differential input resistance 175 kΩ. ESD-protected via input diodes.
3	IN1+	input	Non-inverting input of amplifier 1. Common-mode input voltage range typ ±14 V with ±15 V supplies. ESD-protected via input diodes.
4	VEE	power_in	Negative supply rail. Operating range from -5 V to -18 V for dual-supply operation; total VCC-to-VEE must not exceed 36 V. Typical quiescent supply current 4.1 mA.
5	IN2+	input	Non-inverting input of amplifier 2. Common-mode input voltage range typ ±14 V with ±15 V supplies. ESD-protected via input diodes.
6	IN2-	input	Inverting input of amplifier 2. Typical input bias current 300 nA, input offset current 25 nA, differential input resistance 175 kΩ. ESD-protected via input diodes.
7	OUT2	output	Output of amplifier 2. Class-AB bipolar output stage capable of ±14.1 V swing into 10 kΩ, source ~+29 mA / sink ~-37 mA short-circuit current at ±15 V supplies.
8	VCC	power_in	Positive supply rail. Operating range from +5 V to +18 V for dual-supply operation; total VCC-to-VEE must not exceed 36 V. Typical quiescent supply current 4.1 mA.

3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33078dr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`mc33078dr2g-etched.step`	2.7 MB	You want the part with `MC33078DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 636 faces against 147 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.
