HG5532M 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	OUT1	output	Output of op-amp channel 1. Output voltage swing typ ±14V with RL>10kΩ, ±13V with RL>2kΩ at Vcc=±15V.
2	IN1(-)	input	Inverting input of op-amp channel 1. Input bias current typ 30nA, input offset current typ 5nA, input common-mode range typ ±13V.
3	IN1(+)	input	Non-inverting input of op-amp channel 1. Input bias current typ 30nA, input common-mode range typ ±13V.
4	Vee	power_in	Negative supply rail (Vee). Typical operation at -15V; absolute maximum total supply voltage 22V (Vcc-Vee).
5	IN2(+)	input	Non-inverting input of op-amp channel 2. Input bias current typ 30nA, input common-mode range typ ±13V.
6	IN2(-)	input	Inverting input of op-amp channel 2. Input bias current typ 30nA, input offset current typ 5nA, input common-mode range typ ±13V.
7	OUT2	output	Output of op-amp channel 2. Output voltage swing typ ±14V with RL>10kΩ, ±13V with RL>2kΩ at Vcc=±15V.
8	Vcc	power_in	Positive supply rail (Vcc). Typical operation at +15V; absolute maximum total supply voltage 22V (Vcc-Vee). Supply current typ 5.5mA, max 9.0mA.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hg5532m.step`	122 KB	You want the bare part, or you mark your own boards.
`hg5532m-etched.step`	1.8 MB	You want the part with `HG5532M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 434 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.
