TPA3255 bluetooth high power digital power amplifier(300W+300W)
Product description:
TPA3255 is a high-performance class D power amplifier chip, which has class D efficiency and can bring real high-end sound quality circuits. This 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 and can drive up to two 315W/4R loads and two 150W loads when the THD is 10%(Unclipped power)/8R load, and a unique 2 VRMS analog input interface, supporting high-performance DAC(For example, TI''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s PCM5242)seamless connection. In addition to excellent audio performance, TPA3255 also combines high power efficiency and ultra-low power level idle loss(Less than 2.5W)Two major advantages. 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.
