Power-Supply and Layout Considerations
Bypass the analog and digital power supplies by using a
10μF capacitor in parallel with a 0.1μF capacitor to AGND
and DGND (Figure 10). Minimize lead lengths to reduce
lead inductance. Use shielding and/or ferrite beads to fur-
ther increase isolation.
Digital and AC transient signals coupling to AGND can
create noise at the output. Connect AGND to the high-
est quality ground available. Use proper grounding
techniques, such as a multilayer board with a low-
inductance ground plane. Wire-wrapped boards and
sockets are not recommended. For optimum system
performance, use PC boards with separate analog and
digital ground planes. Connect the two ground planes
together at the low-impedance power-supply source.
Using separate power supplies for AV
DD
and DV
DD
improves noise immunity. Connect AGND and DGND at
the low-impedance power-supply sources (Figure 11).
