TPA3255 Class D Digital Mono Amplifier Board DC24-48V  600W（Radiator models）

 

Note: Currently the fan has been discontinued, now the board is installed on top of the heatsink, not the fan, please know, thank you!


Product Description:

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 up to one 600W/2R load at 10% THD, and features a 2 VRMS analog input interface that supports seamless connection to high-performance DACs such as TI's PCM5242. In addition to excellent audio performance, the TPA3255 also combines the benefits of high power 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 provides a significant reduction in idle losses compared to traditional discrete implementations.
