TPA3250D2DDWR General Description

The TPA3250 device is a high performance class-D power amplifier that enables true premium sound quality with class-D efficiency. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra low distortion across the audio band and superior audio quality. With a 32V power supply the device can drive up to 2 × 130 W peak into 4-Ω load and 2 × 70 W continuous into 8-Ω load and features a 2 VRMS analog input interface that works seamlessly with high performance DACs such as TIs PCM5242. In addition to excellent audio performance, TPA3250 achieves both high power efficiency and very low power stage idle losses below 1 W. This is achieved through the use of 60 mΩ MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
