HT2374ARTZ8 from HTCSEMI, in a SOT-23-8. 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	Output of amplifier channel A. Rail-to-rail push-pull CMOS output, capable of ~50 mA output current and ~80 mA short-circuit current; typical output swing within 10 mV of the supply rails.
2	-IN A	input	Inverting input of amplifier channel A. High-impedance CMOS input (RIN > 100 GOhm, CIN ~1.5 pF differential); common-mode range 0 V to VDD-0.1 V.
3	+IN A	input	Non-inverting input of amplifier channel A. High-impedance CMOS input (RIN > 100 GOhm); common-mode range 0 V to VDD-0.1 V.
4	V-	power_in	Negative supply / ground reference. Tie to 0 V for single-supply operation; total supply (V+ minus V-) must be 2.5 V to 5.5 V (6 V absolute max).
5	+IN B	input	Non-inverting input of amplifier channel B. High-impedance CMOS input; common-mode range 0 V to VDD-0.1 V.
6	-IN B	input	Inverting input of amplifier channel B. High-impedance CMOS input; common-mode range 0 V to VDD-0.1 V.
7	OUT B	output	Output of amplifier channel B. Rail-to-rail push-pull CMOS output, capable of ~50 mA output current and ~80 mA short-circuit current.
8	V+	power_in	Positive supply pin. Single supply 2.5 V to 5.5 V (6 V absolute max). Bypass with a local decoupling capacitor to V-.
