4. Typical Application Schematic¶

This schematic illustrates the typical connection method for the A316-Codec-V1 module in USB microphone applications. The module connects to a host device (such as a computer or smartphone) through the USB interface, enabling bidirectional digital audio transmission. External input only requires 5V power supply, and the module's internal DC-DC power management circuit automatically converts to the operating voltages required by the XU316 and 88L21. The microphone input port supports connecting single-ended or differential microphones, and the stereo output can connect to headphones. The module's integrated high-performance codec ensures audio quality while simplifying external circuit design.
