RS8052XK from Jiangsu RUNIC Tech, 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	Op-amp channel A output. Rail-to-rail output driver, short-circuit current typically ±30 mA; output should be current-limited to ≤55 mA.
2	-INA	input	Inverting input, channel A. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
3	+INA	input	Noninverting input, channel A. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
4	V-	power_in	Negative (lowest) power supply. Together with V+ sets the supply span Vs = (V+) − (V−), rated 1.4 V to 5.5 V (absolute max 7 V). Typically ground in single-supply operation.
5	+INB	input	Noninverting input, channel B. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
6	-INB	input	Inverting input, channel B. Rail-to-rail CMOS input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs = 5.5 V); clamp current must stay ≤10 mA.
7	OUTB	output	Op-amp channel B output. Rail-to-rail output driver, short-circuit current typically ±30 mA; output should be current-limited to ≤55 mA.
8	V+	power_in	Positive (highest) power supply. Together with V− sets the supply span Vs = (V+) − (V−), rated 1.4 V to 5.5 V (absolute max 7 V). Bypass with 100 nF to V−.
