The TPA3255 is a high performance Class D power amplifier that delivers Class D efficiency and high-end sound quality.The device features an integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra HD).This technology allows the device to maintain ultra-low distortion across the audio band while delivering sound quality. The device operates in AD mode and can drive two 315W/4R loads and two 150W (uncut power)/8R loads at 10% , and features a 2 VRMS analog input interface for seamless connection to high-performance DACs such as TI's PCM5242.In addition to excellent audio performance, the TPA3255 also combines efficiency and ultra-low power-level idle losses (less than 2.5W). This is achieved with an 85mR MOSFET and an optimized gate driver scheme. This solution significantly reduces idle losses compared to traditional discrete implementationsColour:As ShownMaterial:PCBPackage Contents:1 * TPA3255 Digital Amplifier Audio BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
