Use the DAC5652EVM layout as reference to obtain the best performance. A sample layout is shown in in the Figure 12-1 through Figure 12-4. 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.
