10.1 Layout Guidelines
Use the DAC5652AEVM layout as a reference to obtain the best performance. A sample layout is shown in Figure 23 through Figure 26. Some important layout recommendations are:
- 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.
- Keep the analog outputs as far away from the switching clocks and digital signals as possible. This keeps coupling from the digital circuits to the analog outputs to a minimum.
- Keep decoupling capacitors close to the power pins of the device.
