9.1 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 TLV320DAC3100 thermal pad must be connected to analog output driver ground using multiple VIAS to minimize impedance between the device and ground.
  • Analog and digital grounds must be separated to prevent possible digital noise form affecting the analog performance of the board.
  • The TLV320DAC3100 requires the decoupling capacitors to be placed as close as possible to the device power supply terminals.
