12.1 Layout Guidelines

The EVM layout optimizes for thermal dissipation and EMC performance. The TAS5411-Q1 device has a thermal pad down, and good thermal conduction and dissipation require adequate copper area. Layout also affects EMC performance. TAS5411Q1EVM illustrations form the basis for the layout discussions.
