A good PCB layout for the TAS5631BPHDR involves keeping the power supply lines (VIN, VCC) separate from the analog signal lines, using a solid ground plane, and placing the decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
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. Also, minimize the thermal resistance of the PCB by using thermal vias and a thermal plane.
The recommended input clock frequency for the TAS5631BPHDR is between 256 kHz and 512 kHz. However, the device can operate with clock frequencies up to 1 MHz, but with reduced performance.
The TAS5631BPHDR 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 audio signal on both channels, while in stereo mode, it outputs separate audio signals on each channel.
The maximum power output of the TAS5631BPHDR is 20 W per channel into a 4-ohm load, with a maximum current output of 2.5 A per channel.
