HGV8632M from HGSEMI, 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 swing; can swing to within ~2mV of the rails with >100kOhm loads and within ~60mV with 10kOhm loads.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input common-mode range extending 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input common-mode range extending 100mV beyond the supply rails.
4	VSS	power_in	Negative supply / ground. Absolute max VDD-to-VSS is 7.5V. For single-supply operation, tie to ground; for dual supply, use -1.05V to -2.75V.
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input common-mode range extending 100mV beyond the supply rails.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input common-mode range extending 100mV beyond the supply rails.
7	OUTB	output	Amplifier B output. Rail-to-rail output swing; drives up to ~53mA typical output current.
8	VDD	power_in	Positive supply. Operating range 2.1V to 5.5V (single-supply) or +1.05V to +2.75V (dual-supply). Bypass with a 0.1uF ceramic capacitor located close to the pin.
