EG8546 from EG Micro, in a SOP-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	OUTA	output	Op-amp A output.
2	INA-	input	Op-amp A inverting (negative) input.
3	INA+	input	Op-amp A non-inverting (positive) input.
4	GND	power_in	Ground / negative supply reference.
5	INB+	input	Op-amp B non-inverting (positive) input.
6	INB-	input	Op-amp B inverting (negative) input.
7	OUTB	output	Op-amp B output.
8	VCC	power_in	Positive supply, 2.5 V to 5.5 V (absolute maximum 6 V).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`eg8546.step`	122 KB	You want the bare part, or you mark your own boards.
`eg8546-etched.step`	1.7 MB	You want the part with `EG8546` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 407 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.
