Layout, Grounding, and Bypassing
Careful printed circuit board layout is essential for best
system performance. For best performance, use a
ground plane. To reduce crosstalk and noise injection,
keep analog and digital signals separate. Digital
ground lines can run between digital signal lines to
minimize interference. Connect analog grounds and
DGND in a star configuration to AGND. For noise-free
operation, ensure the ground return from AGND to the
supply ground is low impedance and as short as possi-
ble. Connect the logic grounds directly to the supply
ground. Bypass V
DD
with 0.1μF and 4.7μF capacitors
to AGND to minimize high- and low-frequency fluctua-
tions. If the supply is excessively noisy, connect a 5
resistor between the supply and V
DD
, as shown in
Figure 12.
