TP8542ARZ from TECH PUBLIC, 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 CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA.
2	INA-	input	Amplifier A inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
3	INA+	input	Amplifier A non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
4	VSS	power_in	Negative supply / ground. Typically tied to 0 V in single-supply operation. Absolute maximum VDD-to-VSS = 7 V; input voltage range VSS-0.5 V to VDD+0.5 V.
5	INB+	input	Amplifier B non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
6	INB-	input	Amplifier B inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
7	OUTB	output	Amplifier B output. Rail-to-rail CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA.
8	VDD	power_in	Positive supply, +2.5 V to +5.5 V single-supply operation (absolute max 7 V VDD-to-VSS). Typical quiescent current 40 uA per amplifier (80 uA total). Bypass with a local ceramic decoupling capacitor.
