Introduction

AI Translation

The TPA3245 is a high-performance Class-D power amplifier that combines Class-D efficiency with true high-end audio quality. The device features an advanced integrated feedback design and a proprietary high-speed gate driver error correction function (PurePath Ultra-HD). This technology enables the device to maintain ultra-low distortion across the entire audio band while delivering pristine audio quality. Operating in AD mode, the device can drive up to 2 loads at 115W/4Ω and 2 loads at 145W/3Ω, and features a 2 VRMS analog input interface for seamless integration with high-performance DACs such as TI's PCM5242. In addition to exceptional audio performance, the TPA3245 offers both high power efficiency and ultra-low power stage idle loss (below 0.45W). This is achieved through 65mΩ MOSFETs and an optimized gate driver solution that significantly reduces idle loss compared to conventional discrete implementations.
