10 Layout

10.1 Layout Guidelines

  • The TAS5558 uses the PCB as a heat sink; therefore, the PowerPAD must be soldered to the PCB, and adequate copper areas and copper vias connecting the top, bottom, and internal layers should be used.
  • Decoupling capacitors should be placed as close to the DVDD1_CORE, DVDD2_CORE, VR_DIG, AVDD_PWM and AVDD as possible. These decoupling capacitors should also have a path through the GND plane back to the power pad, as shown by the blue area in the layout example in Figure 53.
  • A single common GND plane between AGND and DGND is recommended to avoid a potential voltage difference between them. Multiple vias from the TAS5558 PowerPAD should be connected to GND with a large copper pad as well as vias to all GND planes.
  • Further guidelines can be found on the layout example in Figure 53.
  • A more detailed example of the PCB layout can be found in the TAS5548EVM User's Guide (SLOU351).
