TPA3255 Four Channel High Power 150W-350W Digital Class D Audio Amplifier Board

Description

TPA3255 Four Channel Digital Amplifier Board
TPA3255 is a high-performance class D power amplifier, which has class D efficiency and can bring high-end sound quality. The device features an advanced integrated feedback design and a proprietary high-speed gate driver error correction function (PurePath™ Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting perfect sound quality. The device operates in AD mode. When THD is 10%, it can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface to support high-performance DAC (Eg TI's PCM5242) seamless connection. In addition to excellent audio performance, TPA3255 also has two advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved by 85mR MOSFET and optimized gate driver scheme. Compared with the traditional discrete implementation scheme, this scheme can significantly reduce idle loss.
