Design Notes
Ensure a solid ground plane under the TAS5827RHBR to minimize noise and provide a low-impedance return path. Place decoupling capacitors (0.1uF and 10uF) close to the PVDD, AVDD, and DVDD pins. The exposed thermal pad must be soldered to a copper area with thermal vias to dissipate heat effectively.
At 43W output, the TAS5827RHBR can dissipate significant power. Use a PCB with adequate copper area and thermal vias to keep the junction temperature within limits. The VQFN package's thermal pad is essential for heat transfer. For continuous high-power operation, consider adding a heatsink or forced airflow.
Avoid routing sensitive audio input traces near switching output traces to prevent noise coupling. Ensure the digital input signals (MCLK, LRCLK, BCLK, DIN) are properly terminated and have matched trace lengths. In hardware control mode, set the configuration pins correctly before power-up to avoid unintended operation.
