2.1 Channel TPA3251D2 Bluetooth 5.1 220W*2+350W HIFI Power Sound Amplifier Board Module Treble Bass Subwoofer

2.0-channel high-performance class D power amplifier, bringing true high-end sound quality.|Working voltage: DC 24-48V, recommended voltage 36V.|It has an advanced integrated feedback design and a proprietary high-speed gate driver error correction function.This technology enables the device to maintain ultra-low distortion over the entire audio frequency band while presenting high sound quality.|The device operates in AD mode.When the THD is 10%, it can drive a maximum of 2315W/4Q load and 2150w (uncut power)/8Q load, and has a 2 VRMS analog input interface that supports seamless connection of high-performance DACs.|It has high power efficiency and ultra-low power stage idle loss (<2.5W).This can be driven by an 85mR MOSFET and an optimized gate?The actuator scheme is implemented.Compared with the traditional discrete implementation, this scheme can significantly reduce idle loss.
