SGM80582XS8G from SGMICRO, in a SOIC-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; swings to within 15mV of the supply rails with a 1kOhm load and delivers 150mA (typ) short-circuit current at Vs=5V.
2	-INA	input	Amplifier A inverting input. Very high input impedance (10^12 Ohm
3	+INA	input	Amplifier A non-inverting input. Very high input impedance (10^12 Ohm
4	-Vs	power_in	Negative supply rail (or ground in single-supply mode). Total supply (+Vs to -Vs) must be within 2.5V to 5.5V (operating) or 2.7V to 5.5V (specified). Absolute maximum +Vs to -Vs = 6V.
5	+INB	input	Amplifier B non-inverting input. Very high input impedance (10^12 Ohm
6	-INB	input	Amplifier B inverting input. Very high input impedance (10^12 Ohm
7	OUTB	output	Amplifier B output. Rail-to-rail output stage; swings to within 15mV of the supply rails with a 1kOhm load and delivers 150mA (typ) short-circuit current at Vs=5V.
8	+Vs	power_in	Positive supply rail. Total supply (+Vs to -Vs) must be within 2.5V to 5.5V (operating) or 2.7V to 5.5V (specified). Quiescent current is 4.5mA per amplifier (typ). Thermal shutdown activates at 150C.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sgm80582xs8g.step`	122 KB	You want the bare part, or you mark your own boards.
`sgm80582xs8g-etched.step`	3.3 MB	You want the part with `SGM80582XS8G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 753 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.
