TI TPA3250D2DDWR

The TPA3250 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 proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology enables ultra-low distortion across the entire audio band while delivering exceptional sound quality. The device can drive up to 2 × 130W (peak power)/4Ω loads and 2 × 70W (continuous power)/8Ω loads, and features a 2VRMS analog input interface for seamless integration with high-performance DACs such as TI's PCM5242. In addition to outstanding audio performance, the TPA3250 offers both high power efficiency and ultra-low power stage idle dissipation (below 1W). This is achieved through 60mΩ MOSFETs and an optimized gate driver solution, which significantly reduces idle dissipation compared to conventional discrete implementations.
