GS8052-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	Op-amp A output. Rail-to-rail output with ~0.12V swing from rail at RL=150Ω; drives up to 80mA min output current.
2	INA-	input	Op-amp A inverting input. Analog input voltage must remain within Vss-0.5V to VDD+0.5V; input bias current is typically 1pA.
3	INA+	input	Op-amp A non-inverting input. Input common-mode voltage range is -0.2V to +3.8V (typ) on a 5V supply.
4	VSS	power_in	Negative supply rail (or ground for single-supply operation). Absolute max VDD-VSS is +7.5V; typical single-supply operation from +2.5V to +5.5V referenced to VSS=0V.
5	INB+	input	Op-amp B non-inverting input. Input common-mode voltage range is -0.2V to +3.8V (typ) on a 5V supply.
6	INB-	input	Op-amp B inverting input. Analog input voltage must remain within Vss-0.5V to VDD+0.5V; input bias current is typically 1pA.
7	OUTB	output	Op-amp B output. Rail-to-rail output with ~0.12V swing from rail at RL=150Ω; drives up to 80mA min output current.
8	VDD	power_in	Positive supply rail. Operating range +2.5V to +5.5V (single-supply); absolute max +7.5V referenced to VSS. Quiescent current is 2.8mA per amplifier (typ).
