LAYOUT AND POWER SUPPLY BIASING
It is a good practice to employ a compact, minimum lead-length
layout design. The leads to the input should be as direct as
possible, with a minimum conductor length. Ground paths
should have low resistance and low inductance.
Similarly, it is also good practice to bypass the power supplies
with quality capacitors. Low ESR (equivalent series resistance)
1 μF to 10 μF tantalum or electrolytic capacitors should be
applied at the supplies to minimize transient disturbances and
filter low frequency ripple. Figure 31 illustrates the basic supply
bypassing configuration for the AD7376.

The ground pin of the AD7376 is a digital ground reference. To
minimize the digital ground bounce, the AD7376 digital ground
terminal should be joined remotely to the analog ground (see
Figure 31).
