4. Typical Application Schematic¶

This schematic shows the typical connection method of the A316-Codec-V1 module in USB microphone applications. The module connects to host devices (such as computers or smartphones) via USB interface, enabling bidirectional transmission of digital audio. Only 5V power input is required externally, and the module's internal DC-DC power management circuit automatically converts to the operating voltages required by XU316 and 88L21. The microphone input port supports single-ended or differential microphone connections, and the stereo output can connect to headphones. The integrated high-performance codec in the module ensures audio quality while simplifying external circuit design.
