Texas Instruments  TPA3129D2EVM

The TPA3129D2EVM allows for the evaluation of the TPA3129D2. This is an efficient class D audio power amplifier for driving 2 bridged-tied stereo speakers at 30W per channel. The TPA3129D2 has low idle power loss and helps to extend the battery-life of Bluetooth/Wireless speaker and other battery powered audio system. The evaluation module is populated with only 1 TPA3129D2 device and operates from a single power supply from 4.5V to 26V.

The TPA3129D2 devices are fully protected against faults with short-circuit protection and thermal protection with an auto recovery feature. The TPA3129D2 device support Parallel BTL Mode and Mono-Channel Mode.
