AD8552M 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, short-circuit limit 60 mA, output current 65 mA typ.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input range (VSS-0.5 V to VDD+0.5 V abs max), input bias current 20 pA typ.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input range, input bias current 20 pA typ.
4	VSS	power_in	Negative supply / ground. Single-supply operation with VDD-VSS from 1.8 V to 5.5 V (7.5 V abs max).
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input range, input bias current 20 pA typ.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input range, input bias current 20 pA typ.
7	OUTB	output	Amplifier B output. Rail-to-rail output, short-circuit limit 60 mA, output current 65 mA typ.
8	VDD	power_in	Positive supply. 1.8 V to 5.5 V single-supply operation (7.5 V abs max). Quiescent current 180 µA per amplifier typ.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8552m.step`	122 KB	You want the bare part, or you mark your own boards.
`ad8552m-etched.step`	1.7 MB	You want the part with `AD8552M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 426 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.
