GS6002-SR from Gainsil, 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, can source ~84mA and sink ~75mA (typ) into a 10Ω load to VS/2.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input, allowed range VSS-0.1V to VDD+0.1V. Typical input bias current 1pA.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input, allowed range VSS-0.1V to VDD+0.1V. Typical input bias current 1pA.
4	VSS	power_in	Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation uses ±0.9V to ±3V. Bypass with a 0.1µF ceramic capacitor close to the pin in dual-supply mode. Absolute max VDD-VSS = 7.5V.
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input, allowed range VSS-0.1V to VDD+0.1V. Typical input bias current 1pA.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input, allowed range VSS-0.1V to VDD+0.1V. Typical input bias current 1pA.
7	OUTB	output	Amplifier B output. Rail-to-rail output swing, can source ~84mA and sink ~75mA (typ) into a 10Ω load to VS/2.
8	VDD	power_in	Positive supply. Single-supply operating range 1.8V to 6V. Bypass with a 0.1µF ceramic capacitor close to the pin. Absolute max VDD-VSS = 7.5V.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gs6002-sr.step`	122 KB	You want the bare part, or you mark your own boards.
`gs6002-sr-etched.step`	2.4 MB	You want the part with `GS6002-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 566 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.
