Overview

The TPA3128D2EVM allows for the evaluation of the TPA3128D2. This is an efficient class D audio power amplifier for driving 2 bridged-tied stereo speakers at 30W per channel.  The TPA3128D2 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 TPA3128D2 device. It operates from a single power supply from 4.5V to 26V.  The TPA3128D2 devices are fully protected against faults with short-circuit protection and thermal protection with an auto recovery feature.

The TPA3128D2 device supports Parallel BTL Mode and Mono-Channel Mode.
