HIFI Digital Power Amplifier Board Professional 2.0 Channel Class D Stereo Sound 600W TPA3255 Amplifier Module

Feature: 1. High Performance: TPA3255 chip is a high performance amplifier chip, which has class D efficiency and can bring real high end sound quality. 2. Integration Feedback, Error Correction: HIFI digital power amplifier board features advanced integrated feedback design and proprietary high speed gate driver error correction function (PurePath™ Ultra HD). 3. Low Distortion Sound: HIFI digital power amplifier board enables the device to maintain ultra low distortion in the whole sound frequency band, while exhibiting sound quality. 4. Loading Capacity: digital power amplifier board works in AD mode, and can drive up to two 315W 4R loads and two 150W (uncut power) 8R loads when THD is 1.5percent . 5. Input Interface, Connection: Digital power amplifier board has a 2 VRMS analog input interface, which supports seamless connection with high performance DAC (such as PCM5242 of TI). 6. High Efficiency and Low Loss: Amplifier board has two advantages: high power efficiency and ultra low idle loss (less than 2.5W). It is realized by 85mR MOSFET and optimized gate driver scheme.
