GS8592-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 stage; typical short-circuit current 43mA, output current 30mA. Swings to within ~5mV of the supply rails under light load.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input, allowed 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 input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ. 20pA.
4	VSS	power_in	Negative supply / ground. For single-supply operation tie to GND; for dual-supply operation connect to the negative rail. Absolute max VDD-VSS = 7.5V.
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input, allowed 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 input, allowed 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; typical short-circuit current 43mA, output current 30mA.
8	VDD	power_in	Positive supply. Operating range +1.8V to +5.5V (single supply) or ±0.9V to ±2.75V (dual supply). Bypass with a 0.1µF ceramic capacitor to VSS placed close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gs8592-sr.step`	122 KB	You want the bare part, or you mark your own boards.
`gs8592-sr-etched.step`	2.4 MB	You want the part with `GS8592-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 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.
