Dual Core TPA3255 BT5.0 High Power 2.1 Channel Amp Subwoofer Audio Amplifier

  

Dual Core TPA3255 BT5.0 High Power 2.1 Channel Amp Subwoofer Audio Amplifier. TPA3255 is a high performance class D power amplifier chip, which has class D efficiency and can bring true high-end sound quality circuit. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PUREPATH) T. This technology enables the device to maintain ultra-low distortion over the entire audio frequency band while displaying perfect sound quality.

The device works in AD mode. When thd is 10%, the device can drive up to two 315w / 4R loads and two 150W (uncut power) / 8R loads, and has a 2 VRMs analog input interface, which supports seamless connection with high-performance DAC (such as TI's pcm5242). In addition to its excellent audio performance, tpa3255 has the advantages of 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 scheme, this scheme can significantly reduce the idle loss.
