Fuhjythy TPA3255 Fever Grade HIFI Digital Power Amplifier Board 300Wx2 Dual Channel High Power Audio Amplifier Module

TPA3255 is a high-performance Class D power amplifier chip with Class D efficiency and a circuit that can bring true high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction. This technology allows the device to maintain ultra-low distortion across the entire audio frequency band while demonstrating sound quality. The device operates in AD mode and can drive up to 2 315W/4R loads and 2 150W (unclipped power)/BR loads at a of 1.5%, and has a 2 VRMS analog input interface to support high-performance (such as TI's PCM5242) seamless connection. the TPA3255 combines high power efficiency with ultra-low power level idle losses (less than 2.5W) two major advantages. This is achieved with 85mR MOSFETs and an optimized gate driver scheme. This solution can significantly reduce idle losses compared to traditional discrete implementations.
