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 implementations Colour:As Shown Material:PCB Package Contents: 1 * TPA3255 Digital Amplifier Audio Board Only the above package content, other products are not included.
