A 2.1-channel digital amplifier board using the TPA3116D2 chip, delivering 50W and 100W channels from a 12V-24V supply

  • TPA3116D2 chip delivers efficient Class D amplification

  • 50 W per satellite and 100 W for subwoofer output
  • Operates from 12 V to 24 V DC supply

Digital amplifier board for 2.1 audio

This DC12V-24V board integrates a TPA3116D2 chip in a 2.1 three-channel layout. It delivers 50W to the subwoofer channel and 100W to the stereo pair. The module suits DIY speaker builds or repairs that need a compact Class D solution. It runs from a 12V to 24V DC supply.

Power input range decides compatibility

The board accepts 12V to 24V DC only; voltages outside that window will not work. Buyers who need a different supply voltage or more output channels cannot use this module. The fixed 50W plus 100W split also limits designs that require balanced power per channel.

Questions about this item

What does the 50W + 100W power rating mean when the board is installed?

The board delivers up to 50 watts to each stereo channel and up to 100 watts to the subwoofer channel when driven within the 12 V to 24 V supply range.

How does the DC 12 V to 24 V input range limit the amplifier's output?

Supplying 12 V limits maximum output power, while 24 V allows the TPA3116D2 to reach the full 50 W per satellite and 100 W for the subwoofer channel.
