2X8Watt TPA3123 Class-D Audio Amplifier Board

this 2*8W also employs TPA3123D2 chip from TI. The efficiency of the TPA3123D2 eliminates the need for an external heat sink when playing music. It supports dual channel amplification and each such channel is rated at 8W which helps producing state-of-the-art sound quality. Integrating high-quality SMD and MKP plug-in capacitors ensures Hi-Fi amplification output.

You can use it to drive any 4Ω or 8Ω passive speakers. It can readily be powered by any DC power supply ranging from +10 to 16V. With a Car Cigarette Lighter Plug Charger, you can enjoy great music in car without extra power supply.
