AD8552MM

HGSEMI · Precision OpAmps · MSOP-8

AD8552MM from HGSEMI, in a MSOP-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 stage; can swing within ~5mV of VSS/VDD with a 10kΩ load. Short-circuit current limit typ. 60mA.
2	INA-	input	Amplifier A inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA.
4	VSS	power_in	Negative supply / ground reference. For single-supply operation tie to GND; supply range 1.8V to 5.5V referenced to VDD (absolute max VDD-VSS = 7.5V).
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA.
6	INB-	input	Amplifier B inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA.
7	OUTB	output	Amplifier B output. Rail-to-rail output stage; can swing within ~5mV of VSS/VDD with a 10kΩ load. Short-circuit current limit typ. 60mA.
8	VDD	power_in	Positive supply. Single-supply range 1.8V to 5.5V (dual ±0.9V to ±2.75V). Decouple with a 0.1µF ceramic close to the pin.

CAD (KiCad official)

Symbol: AD8552MM
Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
3D model: MSOP-8 (KiCad packages3D, STEP)
3D model files: ad8552mm-etched.step / ad8552mm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad8552mm.step / ad8552mm.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8552mm.step`	123 KB	You want the bare part, or you mark your own boards.
`ad8552mm-etched.step`	1.8 MB	You want the part with `AD8552MM` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 455 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.
