SA5532MM from HGSEMI, 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	OUT1	output	Output of op-amp channel 1. Low-impedance analog output, capable of driving typical audio loads (600 Ω).
2	IN1-	input	Inverting input of op-amp channel 1. High-impedance analog input.
3	IN1+	input	Non-inverting input of op-amp channel 1. High-impedance analog input.
4	VCC-	power_in	Negative supply rail (or GND in single-supply operation). Total supply range ±3 V to ±22 V (6 V to 44 V single-supply).
5	IN2+	input	Non-inverting input of op-amp channel 2. High-impedance analog input.
6	IN2-	input	Inverting input of op-amp channel 2. High-impedance analog input.
7	OUT2	output	Output of op-amp channel 2. Low-impedance analog output, capable of driving typical audio loads (600 Ω).
8	VCC+	power_in	Positive supply rail. Total supply range ±3 V to ±22 V (6 V to 44 V single-supply).
