10.1 Layout Guidelines
Printed circuit board (PCB) design is made considering the application, and the review is specific for each system requirements. However, general considerations can optimize the system performance:
- Connect the TLV320AIC3109-Q1 thermal pad to the analog output driver ground
- Separate the analog and digital grounds to prevent possible digital noise from affecting the analog performance of the board
- The TLV320AIC3109-Q1 requires the decoupling capacitors to be placed as close as possible to the device power-supply terminals
- If possible, route the differential audio signals differentially on the PCB to obtain better noise immunity
