GS8052-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, typically swings to within 8mV of the supply rails into >1kΩ loads and 30mV into 150Ω loads. Sources/sinks up to 80mA (min 60mA).
2	INA-	input	Amplifier A inverting input. High-impedance CMOS input (typical bias current 1pA). Common-mode voltage range: -0.2V to +3.8V (relative to Vss on a 5V supply).
3	INA+	input	Amplifier A non-inverting input. High-impedance CMOS input (typical bias current 1pA). Must remain within Vss-0.5V to VDD+0.5V absolute maximum.
4	VSS	power_in	Negative supply / ground. Tie to GND for single-supply operation, or to -1.25V to -2.75V for dual-supply operation. Bypass to ground with a 0.1µF ceramic close to the pin (dual-supply case).
5	INB+	input	Amplifier B non-inverting input. High-impedance CMOS input (typical bias current 1pA). Must remain within Vss-0.5V to VDD+0.5V absolute maximum.
6	INB-	input	Amplifier B inverting input. High-impedance CMOS input (typical bias current 1pA). Common-mode voltage range: -0.2V to +3.8V (relative to Vss on a 5V supply).
7	OUTB	output	Amplifier B output. Rail-to-rail output, typically swings to within 8mV of the supply rails into >1kΩ loads and 30mV into 150Ω loads. Sources/sinks up to 80mA (min 60mA).
8	VDD	power_in	Positive supply. +2.5V to +5.5V single-supply operating range (absolute max +7.5V referenced to VSS). Bypass to ground with a 0.1µF ceramic capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gs8052-sr.step`	122 KB	You want the bare part, or you mark your own boards.
`gs8052-sr-etched.step`	2.4 MB	You want the part with `GS8052-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 573 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.
