TPA3255 315W+315W Hifi Digital Amplifier Board Power Amp Board Audio Amplifier for DIY Projects
Description:
The new amplifier board improves the problem of high voltage protection, and it works normally when 52V is used. Hifi components are also used. Auxiliary power supply is a class A linear power supply, which is more dynamic and sound quality is significantly improved! The amplifier board can drive 2-16 ohm speakers. With the same power supply, the output power is increased by up to 50%.
TPA3255 is a high-performance class D power amplifier chip. It has a circuit with class D efficiency and is capable of delivering truly high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (for PurePath Ultra HD). This technology allows the device to maintain ultra-low distortion over the entire audio frequency band while exhibiting sound quality.
Operating in AD mode, it drives up to two 315W/4R loads and two 150W (unclipped power)/8R loads at 1.5% THD. It also features a 2VRMS analog input interface that allows seamless interfacing with high-performance DACs such as PCM5242 for TI. In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power stage idle loss (less than 2.5W). This can be achieved with 85mR MOSFETs and an optimized gate driver scheme. The scheme significantly reduces idle losses compared to traditional discrete implementations.
