Power-Supply Bypassing and
Ground Management
For optimum performance, use a multilayer PC board
with an unbroken analog ground. For normal opera-
tion, when all AGND_ pins are at the same potential,
connect the four AGND_ pins directly to the ground
plane or connect them together in a “star” configura-
tion. The center of this star point is a good location to
connect the digital system ground with the analog
ground.
If you are using a single common reference voltage,
you can connect the reference inputs together using a
“star” configuration. If you are using DC reference volt-
ages, bypass each reference input with a 0.1F to 1F
capacitor to AGND_.
