Overview
The TPA3113D2PWPR is a 6-W (per channel) efficient, Class-D audio power amplifier produced by Texas Instruments. This amplifier is designed for driving bridged-tied stereo speakers and features advanced EMI Suppression Technology, allowing the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. The device operates on a single power supply between 8 V and 26 V, eliminating the need for heat sinks due to its high efficiency of 87% in Class-D operation.
