The Texas Instruments TPA3250D2DDWR is a high-performance Class-D audio amplifier designed for home audio, soundbars, and other audio applications. It delivers up to 70W stereo continuous output power into an 8 ℆ load at 32V supply, with peak power reaching 130W stereo into 4 ℆. The device operates from a wide power stage supply voltage range of 12V to 36V and an analog supply voltage of 10.8V to 13.2V.
Featuring PurePath™ Ultra-HD technology, the TPA3250D2DDWR offers advanced integrated feedback design with high-speed gate driver error correction, ensuring excellent audio quality with ultra-low total harmonic distortion plus noise (THD+N) of 0.005% at 1W into 4 ℆. The signal bandwidth extends up to 100 kHz, accommodating high-frequency content from HD sources. The amplifier supports multiple configurations, including stereo, mono, 2.1, and 4xSE, and provides click and pop-free startup and stop.
Encased in an HTSSOP (DDW) package, this amplifier operates within a temperature range of 0 to 70 °C. It includes self-protection features such as undervoltage, overtemperature, clipping, and short circuit protection with error reporting, contributing to reliable operation. The high efficiency of 92% Class-D operation makes it suitable for power-sensitive applications.
