A good PCB layout for the TAS5631BDKDR involves keeping the power supply and output stages separate, using a star-ground configuration, and minimizing the length of the power traces. TI provides a recommended PCB layout in the datasheet and application notes.
To optimize thermal performance, ensure good airflow around the device, use a heat sink if possible, and avoid blocking the thermal pads on the bottom of the package. TI also provides thermal design guidelines in the datasheet.
The recommended input clock frequency for the TAS5631BDKDR is between 256 kHz and 512 kHz. However, the device can operate with clock frequencies up to 1 MHz, but with reduced performance.
The TAS5631BDKDR can be configured for mono or stereo operation by setting the MODE pin high or low, respectively. In mono mode, the device outputs the same signal on both channels, while in stereo mode, it outputs separate signals on each channel.
The maximum power supply voltage for the TAS5631BDKDR is 15.5 V. Operating the device above this voltage can cause damage or reduce its lifespan.
