HXV8542DGKRG from HANSCHIP semiconductor, 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	OUT A	output	Amplifier A output. Rail-to-rail output stage, sources/sinks up to ~15 mA (Vs=2.7 V) / ~18 mA (Vs=5 V). VOL <= 100 mV at IL=1 mA; closed-loop Zout ~50 ohm at 200 kHz, Av=1.
2	-IN A	input	Amplifier A inverting input. Rail-to-rail input, IB typ 4 pA, IOS typ 0.1 pA. Input common-mode range 0 V to Vs.
3	+IN A	input	Amplifier A non-inverting input. Rail-to-rail input, IB typ 4 pA. Input common-mode range extends 0 V to Vs.
4	V-	power_in	Negative supply / ground. Tie to GND in single-supply operation. Total supply voltage V+ minus V- must not exceed 6 V (absolute max).
5	+IN B	input	Amplifier B non-inverting input. Rail-to-rail input, IB typ 4 pA. Input common-mode range extends 0 V to Vs.
6	-IN B	input	Amplifier B inverting input. Rail-to-rail input, IB typ 4 pA, IOS typ 0.1 pA. Input common-mode range 0 V to Vs.
7	OUT B	output	Amplifier B output. Rail-to-rail output stage, sources/sinks up to ~15 mA (Vs=2.7 V) / ~18 mA (Vs=5 V). VOL <= 100 mV at IL=1 mA; closed-loop Zout ~50 ohm at 200 kHz, Av=1.
8	V+	power_in	Positive supply, 2.7 V to 5.5 V single-supply operation (6 V absolute max). Quiescent current ~38 uA/amplifier (typ), ~55 uA max at 25 C. Bypass with a local 0.1 uF ceramic to V-.
