In this design, each half-bridge uses four mosfets(M1-M4), and the capacitor "flying" between them as an additional power supply rail, thereby generating a three-level output signal at the output switch node. Built-in Bluetooth 5.0 Supports apt-X and AAC, Using Qualcomm's modular Bluetooth solution, built-in Bluetooth antenna, signal stability and transmission quality have been improved in all directions. Let HiFi push towards wireless. Driver-free USB input design The accessory provides a USBcable dedicated for A100, which can be directly plugged into the computer to play songs. It supports multiple formats of music files. MP3, SBC, WAV and FLAC can be played easily.
