13 Layout

13.1 Layout Guidelines

PCB design is made considering the application, and the review is specific for each system requirements. However, general considerations can optimize the system performance.

  • The TLV320AIC3107IRSB thermal pad should be connected to analog output driver ground using multiple VIAS to minimize impedance between the device and ground.
  • SPVSS balls of TLV320AIC3107IYZF are recommended to be soldered directly to Class-D ground.
  • SPVSS balls of TLV320AIC3107IYZF are recommended to be soldered directly to Class-D ground.
  • The TLV320AIC3107 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. This is recommended to get better noise immunity.
