TPA3255 Digital Power Amplifier Audio Amp Assembled Board 300W + 300W Class D


Features:

The TPA3255 is a powerful Class D power amplifier with a D-class efficiency rating and true high-end sound quality. The device features an advanced integrated feedback design and proprietary gate driver error correction function (PurePath ™ Ultra HD). This technology allows the device to maintain extremely low distortion throughout the audio band while delivering perfect sound quality. The device operates in AD mode with up to two loads of 315 W / 4R and two loads of 150 W (not truncated power) / 8R with a THD of 10%, and has a 2 VRMS analog input interface that supports high performance DAC (such as TI) seamlessly PCM5242). In addition to excellent audio performance, the TPA3255 combines high power efficiency and extremely low idle power loss (less than 2.5W), two main advantages. This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. The scheme can significantly reduce the open-circuit loss relative to the conventional discrete implementation scheme.
