Power-Supply and Layout Considerations
Bypass the analog and digital power supplies with a
10μF capacitor in parallel with a 0.1μF capacitor to ana-
log ground (AGND) and digital ground (DGND) (see
Figure 10). Minimize lead lengths to reduce lead induc-
tance. If noise is an issue, use shielding and/or ferrite
beads to increase isolation.
Digital and AC transient signals coupling to AGND cre-
ate noise at the output. Connect AGND to the highest
quality ground available. Use proper grounding tech-
niques, such as a multilayer board with a low-induc-
tance ground plane. Wire-wrapped boards and sockets
are not recommended. For optimum system perfor-
mance, use printed circuit (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 source (see Figure 11).
