GS8592-MR from Gainsil, 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 capable of swinging to within ~5mV of the supply rails under light load (>100kOhm) and 60mV under 10kOhm loads. Short-circuit current limit 43mA typical.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input range (Vss-0.1V to Vdd+0.1V). Input bias current 20pA typ, input offset current 10pA typ.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input range (Vss-0.1V to Vdd+0.1V). Input bias current 20pA typ.
4	VSS	power_in	Negative supply rail (ground in single-supply operation). Absolute max Vdd-to-Vss is 7.5V. Bypass with a 0.1uF ceramic capacitor to ground in dual-supply operation.
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input range (Vss-0.1V to Vdd+0.1V). Input bias current 20pA typ.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input range (Vss-0.1V to Vdd+0.1V). Input bias current 20pA typ, input offset current 10pA typ.
7	OUTB	output	Amplifier B output. Rail-to-rail output stage capable of swinging to within ~5mV of the supply rails under light load (>100kOhm) and 60mV under 10kOhm loads. Short-circuit current limit 43mA typical.
8	VDD	power_in	Positive supply rail. Single-supply range 1.8V to 5.5V (or dual +/-0.9V to +/-2.75V). Absolute max Vdd-to-Vss is 7.5V. Bypass with a 0.1uF ceramic capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gs8592-mr.step`	123 KB	You want the bare part, or you mark your own boards.
`gs8592-mr-etched.step`	2.3 MB	You want the part with `GS8592-MR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 542 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.
