HS6425 zk-3002 TPA3255 300W+300W Class D Amplifier Board Hifi Power Amplifier Board Stereo Power Amp Board/BT5.1 Bluetooth DAC Board
Description:
It completely improves the common problem of high voltage protection. Thus it can work with 50V. More audiophile components are used. The auxiliary power supply uses a class A linear power supply, making it more dynamic and significantly improving the sound quality! It can drive 2-16 ohm speakers!
The TPA3255 is a high-performance Class D power amplifier chip. It has a circuit with Class D efficiency and is capable of delivering truly high-end sound quality. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (Ultra HD for PurePath). This technology allows the component to maintain ultra-low distortion over the entire audio frequency band while exhibiting sound quality. Operating in AD mode, the chip drives up to two 315W/4R loads and two 150W (unclipped power)/8R loads at 1.5% THD, and features a 2 VRMS analog input interface that allows seamless interfacing with high-performance DACs such as the PCM5242 for TI.
In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power stage idle loss (less than 2.5W). This can be achieved with 85mR MOSFETs and an optimized gate driver scheme. Compared to traditional discrete implementations, this scheme significantly reduces idle losses.
