lelisten TPA3116D2 Stereo Amplifier Board 2x50W 12V 24V

SKU CH-2RZ1-97XTR

Dual-channel stereo amplifier board delivers 2x50W output using a TPA3116D2 chip and operates on 12V or 24V DC with built-in protection circuits

  • TypeAmplifiers
  • Stereo sound from a single compact board
  • 2×50 W output drives speakers with authority
  • Wide DC 4.5–26 V input suits 12 V or 24 V supplies
  • Built-in short-circuit, thermal and voltage protections prevent damage
  • High-performance inductors and capacitors ensure clean amplification

Stereo amplifier for DIY speaker builds

This lelisten board uses the TPA3116D2 chip to deliver two channels at 50 W each. It accepts a DC supply from 4.5 V up to 26 V, with 24 V recommended for full output. Built-in reverse-connection protection guards the circuit during assembly.

Ideal for compact audio projects.

Hobbyists building bookshelf speakers, small home-theatre satellites or shop announcement systems will appreciate the simple two-channel layout and wide voltage range. Installers needing more than 50 W per channel or multi-zone distribution should look at larger amplifier modules.

50 W per channel into 4–8 Ω speakers

The rated 2x50 W output is the key figure for matching drivers and power supplies. Ensure your speakers fall within the 4–8 Ω range and that the chosen supply can deliver sufficient current at 12 V or 24 V.

Questions about this item

Will the 2x50W output hold up during long sessions without thermal shutdown?

The board includes thermal protection that activates if the chip overheats, so sustained full-power use may trigger a temporary shutdown until the TPA3116D2 cools.

How hot or noisy does the TPA3116D2 board get when powered at 24V all day?

The amplifier has no fan; heat rises from the chip and inductors during continuous operation, and audible noise depends on the speaker load and enclosure rather than the board itself.

What power supply do I need to run this stereo amplifier at its recommended voltage?

A DC source delivering 24V within the 4.5–26V range is recommended, with enough current headroom for two 50W channels and the board's reverse-connection protection.
