Feature: TPA3255 is a high-performance Class D power amplifier, it has D class efficiency and can bring real high-end sound quality. The device features a highly advanced integrated feedback design and a proprietary high-speed gate driver error correction feature (PurePath ™ Ultra HD).
This technology allows the device to maintain ultra-low distortion throughout the audio band while delivering perfect sound quality.
The device operates in AD mode with up to two 315W / 4R loads and two 150W (non-clipped power) / 8R loads with a THD of 10%, and features a 2 VRMS analog input interface that supports high performance DAC (Such as TI's PCM5242) seamlessly.
In addition to excellent audio performance, TPA3255 also combines high power efficiency and ultra low power idle loss (less than 2.5W) two major advantages.
This can be achieved with a 85mR MOSFET and an optimized gate driver scheme. The scheme can significantly reduce the idle loss relative to the traditional discrete implementation scheme .
Products Details:
1: Adopt the TPA3255
2: The main filter electrolytic capacity is 4700UF / 75V * 2, to ensure a strong stream of continuous power support
