11 Layout

11.1 Layout Guidelines

The DAC5682Z EVM layout should be used as a reference for the layout to obtain the best performance. A sample layout is shown in Figure 53. Some important layout recommendations are:

  1. Use a single ground plane. Keep the digital and analog signals on distinct separate sections of the board. This may be virtually divided down the middle of the device package when doing placement and layout.
  2. Keep the analog outputs as far away from the switching clocks and digital signals as possible. This will keep coupling from the digital circuits to the analog outputs to a minimum.
  3. Decoupling caps should be kept close to the power pins of the device.
