SLES146A – AUGUST 2005 – REVISED OCTOBER 2010
Separate power supplies are recommended for the digital and analog sections of the board. This prevents the
switching noise present on the digital supply from contaminating the analog power supply and degrading the
dynamic performance of the DACs. In cases where a common 5-V supply must be used for the analog and
digital sections, an inductance (RF choke, ferrite bead) should be placed between the analog and digital 5-V
supply connections to avoid coupling of the digital switching noise into the analog circuitry. Figure 35 shows the
recommended approach for single-supply applications.
