HT2348ARTZ8 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	Amplifier A output. Rail-to-rail output stage; can source/sink up to 50 mA typical output current with short-circuit current of 80 mA typical.
2	-IN A	input	Amplifier A inverting input. Rail-to-rail input; common-mode range from 0 V to VDD-0.1 V. Input resistance > 100 GOhm.
3	+IN A	input	Amplifier A non-inverting input. Rail-to-rail input; common-mode range from 0 V to VDD-0.1 V. Input resistance > 100 GOhm.
4	V-	power_in	Negative supply / ground pin. In single-supply operation this is tied to GND; total supply range V+ to V- is 2.5 V to 5.5 V.
5	+IN B	input	Amplifier B non-inverting input. Rail-to-rail input; common-mode range from 0 V to VDD-0.1 V. Input resistance > 100 GOhm.
6	-IN B	input	Amplifier B inverting input. Rail-to-rail input; common-mode range from 0 V to VDD-0.1 V. Input resistance > 100 GOhm.
7	OUT B	output	Amplifier B output. Rail-to-rail output stage; output voltage swings within ~10 mV of the supply rails under a 10 kOhm load.
8	V+	power_in	Positive supply pin. 2.5 V to 5.5 V single-supply operation; quiescent current is 330 uA typical (590 uA max) per amplifier at VDD = 5 V.
