Description
1) It has high efficiency, usually reaching more than 85%;
2) Small in size, it can save a lot of space than analog amplification circuits;
3) No cracking noise connection;
4) Low distortion and good frequency response curve. There are few peripheral components, making it easy to design and debug.
