A good PCB layout is crucial for the TAS5630BDKD. TI recommends a 4-layer PCB with a solid ground plane, and to keep the power traces as short as possible. A good rule of thumb is to keep the power traces within 1 inch of the device. Also, make sure to decouple the power supply with a 10uF capacitor.
The gain setting of the TAS5630BDKD depends on the specific application. A good starting point is to set the gain to 20dB, and then adjust it based on the output power and distortion requirements. It's also important to consider the input impedance and the output load impedance when setting the gain.
The TAS5630BDKD can dissipate up to 15W of power, so proper thermal management is crucial. TI recommends using a heat sink with a thermal resistance of less than 10°C/W, and to ensure good airflow around the device. It's also important to keep the device away from other heat sources.
To minimize EMI, TI recommends using a common-mode choke and a differential-mode filter in the power supply lines. Additionally, make sure to use a shielded cable for the input signal, and to keep the signal traces away from the power traces.
The maximum output power of the TAS5630BDKD depends on the supply voltage and the load impedance. With a 24V supply voltage, the device can deliver up to 125W of output power into a 4Ω load. However, it's important to consider the thermal limitations and the distortion requirements when designing the application.
