TPA3251D2DDV

产品概述

The TPA3251D2DDV is a high performance Class D Power Amplifier 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. The device can drive up to 2 x 175W into 4R load and 2x220W into 3R load and features a 2VRMS analog input interface that works seamlessly with high performance DACs such as TI’s PCM5242. In addition to excellent audio performance, TPA3251 achieves both high power efficiency and very low power stage idle losses below 1W. This is achieved through the use of 60mR MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
