SKU CH-4KPH-ZK2MZ

A mono digital audio amplifier module operating from an 8 to 24 volt DC supply using a TPA3118 chip

  • TPA3118 chip delivers efficient mono amplification
  • PBTL topology maximises output from single module
  • Wide 8-24 V DC input suits many systems
  • Compact board simplifies internal audio integration

Universal DC 8-24V amplifier module

This compact module integrates a TPA3118 chip in PBTL mono configuration for digital audio amplification. It accepts a wide DC input range from 8 to 24 volts, making it suitable for custom speaker builds or repair projects. Hobbyists and DIY audio enthusiasts can incorporate it into portable or powered speaker systems.

Direct replacement for failed mono amp boards

The board serves as a drop-in substitute when an existing single-channel amplifier fails or when upgrading from a lower-power module. The jump is worth it when the original board cannot handle the required supply voltage or output topology. It is not suited for builders who need stereo output or multi-channel processing.
