Texas Instruments  TPA3138D2EVM

The TPA3138D2EVM allows for the evaluation of the TPA3138D2. This is an efficient class D audio power amplifier for driving 2 bridged-tied stereo speakers at 10W per channel. The evaluation module is populated with only 1 TPA3138D2 device. It operates from a single power supply from 4.5V to 14.4V. The TPA3138D2 utilizes advanced EMI suppression technology with spread spectrum control which enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for the system cost reduction. The TPA3138D2 devices are fully protected against faults with short-circuit protection and thermal protection with an auto recovery feature.
