XH-A232 TPA3110 2.0 Channel Digital Stereo Amplifier Board – 30W+30W

The XH-A232 TPA3110 2.0 Channel Digital Stereo Amplifier Board– 30W+30W is a Class D amplifiers switch output transistors at high frequency instead of linearly amplifying the audio signal. That switching approach converts most input power into audio output rather than heat, which is why the TPA3110 2.0 Channel Digital Stereo Amplifier Board runs cool enough at moderate volumes without a large heatsink. The TPA3110 IC handles both stereo channels on one chip, delivering 30W per channel into 4ohm to 8 ohm speakers across a 12V to 24V DC supply range.

Signal-to-noise ratio at 100 dB means the noise floor sits far below the audio signal – background hiss stays inaudible at standard listening levels through most speaker types.The XH-A232 amplifier board requires more than 3A from the power supply at the chosen operating voltage. At 12V, total output approaches the rated 30W+30W – a 12V 5A supply covers that headroom with margin. Connecting this board to a supply rated below 3A causes voltage sag at higher volumes, producing audible distortion before the rated output is reached.

The tpa3110 amplifier board connects directly to any line-level audio source – phone output, DAC, or media player without a preamplifier stage between source and board input. The Digital Stereo Amplifier Board suits desktop speaker builds, Bluetooth receiver integration, and custom audio amplifier prototyping. This xh-a232 digital stereo amplifier board  is available on StemVolt, and its working on DIY audio systems and builds speaker amplifier.
