Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the audio signal traces short and away from the power supply lines, and using a solid ground plane to reduce noise and EMI.
The gain setting depends on the input signal level and the desired output power. The TPA6017A2PWPR has a gain range of 10 dB to 30 dB. You can use the gain equation in the datasheet to calculate the required gain setting for your specific application.
The maximum power dissipation of the TPA6017A2PWPR is dependent on the ambient temperature and the thermal resistance of the PCB. According to the datasheet, the maximum power dissipation is 2.5 W at 25°C ambient temperature. However, it's essential to perform thermal calculations and consider the specific application's requirements.
To filter out noise and EMI, use a combination of passive components, such as capacitors and inductors, and active filtering techniques, such as using op-amps or dedicated audio filters. Additionally, ensure good PCB design practices, such as keeping the audio signal traces short and away from the power supply lines, and using a solid ground plane.
The recommended power supply decoupling for the TPA6017A2PWPR is to use a 10 μF capacitor in parallel with a 100 nF capacitor, both connected between the power supply pins and the ground pin. This helps to filter out noise and ripple on the power supply lines.
