TDA2822M from HGSEMI, 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	1 OUT	output	Channel 1 (left) speaker output. AC-coupled to load through a large electrolytic (typ 100-470 uF) with a 4.7 Ω + 0.1 uF Zobel network to ground. Drives 4-32 Ω loads up to ~1 W BTL or ~450 mW stereo depending on Vcc.
2	Vcc	power_in	Positive supply pin. Operating range 1.8 V to 12 V (typ 3 V); absolute maximum 15 V. Bypass locally with a 10 uF electrolytic capacitor to GND.
3	2 OUT	output	Channel 2 (right) speaker output. AC-coupled to load through a large electrolytic (typ 100-470 uF) with a 4.7 Ω + 0.1 uF Zobel network to ground. Drives 4-32 Ω loads; complementary output to pin 1 in BTL mode.
4	GND	power_in	Ground / 0 V reference for the device and both amplifiers.
5	2 IN-	input	Channel 2 inverting input. In stereo application it is AC-grounded through a 100 uF bypass capacitor to set the closed-loop gain (~40 dB); input impedance ≥100 kΩ, input bias current ~100 nA.
6	2 IN+	input	Channel 2 non-inverting input. Signal input for right channel in stereo mode; tied to GND (with source resistor) in BTL bridge mode. Input impedance ≥100 kΩ.
7	1 IN+	input	Channel 1 non-inverting input. Signal input for left channel in stereo mode; single input in BTL bridge mode. Input impedance ≥100 kΩ, driven from a source ≤10 kΩ typically.
8	1 IN-	input	Channel 1 inverting input. In stereo application AC-grounded through a 100 uF bypass capacitor to set the closed-loop gain (~40 dB); in BTL mode cross-couples to the second amplifier's output to form the bridge.
