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

The device features an advanced 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 entire audio frequency band while demonstrating sound quality. It is now a newly revised product in May 2024. It works completely normally at 52V, and the materials used are more advanced. It can perfectly drive 4-8 ohm speakers! The output power is increased by more than 50% under the same power supply. 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. 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 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.
