OPA2374M from HGSEMI, 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	Amplifier A output. Rail-to-rail output swing capable of driving 600Ω loads to within 0.1V of the supply rails.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input, common-mode range extends from VSS-0.1V to VDD+0.1V.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input, common-mode range extends from VSS-0.1V to VDD+0.1V.
4	VSS	power_in	Negative supply / ground. Typically tied to GND for single-supply operation; VDD-VSS range 2.1V to 5.5V (7.5V abs max).
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input, common-mode range extends from VSS-0.1V to VDD+0.1V.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input, common-mode range extends from VSS-0.1V to VDD+0.1V.
7	OUTB	output	Amplifier B output. Rail-to-rail output swing capable of driving 600Ω loads to within 0.1V of the supply rails.
8	VDD	power_in	Positive supply. Operating range 2.1V to 5.5V (7.5V abs max). Bypass with 0.1µF ceramic near the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa2374m.step`	122 KB	You want the bare part, or you mark your own boards.
`opa2374m-etched.step`	1.6 MB	You want the part with `OPA2374M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 413 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.
