Features: 1. TPA3255 is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring real high-end sound quality circuits.
2. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath UHD)
3. This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting sound quality.
4. The device works in AD mode, when the THD is 1.5%, it can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface, which supports high Performance DACs such as TIs PCM5242 connect seamlessly.
5. In addition to excellent audio performance, TPA3255 also has two advantages of high power efficiency and ultra-low power level idle loss (less than 2.5W)
