2020 Breeze Audio New HiFi 2.0 Class D Full Digital Audio Amplifier TPA-3255A High Power 300W*2/4ohm Bluetooth@5.0 Black Optinal

product manual:

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