Practical digital amplifier (TL084) circuit

Published:2011/7/6 5:42:00 Author:chopper | Keyword: Practical, digital amplifier | From:SeekIC

Conventional home theater digital amplifier requires the special integrated circuit, but such a integrated circuit has few manufacturers,and the high price. The circuit can be made by common components, and power is 50W.There is no power consumption when it is no-load,full load efficiency is about 85%,thus it has a certain practical value.However,the final stage of its power supply adopts floating ground ,the electromagnetic compatibility of the circuit is poor. As the 200kHz carrier does not filter out cleanly, its distortion and the signal to noise ratio and other indicators are still to be improved.
