TDA2822G-S08-R

UTC Unisonic Tech · Audio Power OpAmps · SOIC-8

TDA2822G-S08-R from UTC Unisonic Tech, in a SOIC-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 OUTPUT1 output Amplifier channel 1 speaker output. Drives loads down to 4Ω; delivers ~0.45W (SOP-8, VCC=6V, RL=4Ω, THD=10%) in stereo mode. AC-coupled to load via output capacitor.
2 VCC power_in Positive supply voltage input. Operating range 1.8V to 12V; absolute maximum 15V. Typically bypassed with 100µF to GND.
3 OUTPUT2 output Amplifier channel 2 speaker output. Drives loads down to 4Ω; delivers ~0.45W (SOP-8, VCC=6V, RL=4Ω, THD=10%) in stereo mode. AC-coupled to load via output capacitor.
4 GND power_in Ground/negative supply reference for both amplifier channels.
5 NF2 input Channel 2 negative-feedback (inverting) input. Sets closed-loop gain of ~40 dB via external feedback network; typically bypassed to ground through a 100µF capacitor in stereo mode, or tied through a small capacitor for bridge configuration.
6 INPUT2 input Channel 2 non-inverting audio signal input. Input resistance ~100 kΩ; AC-coupled from source. In bridge mode this pin is tied to ground.
7 INPUT1 input Channel 1 non-inverting audio signal input. Input resistance ~100 kΩ; AC-coupled from source.
8 NF1 input Channel 1 negative-feedback (inverting) input. Sets closed-loop gain of ~40 dB via external feedback network; typically bypassed to ground through a 100µF capacitor in stereo mode.
