POWER SUPPLY DECOUPLING
In any circuit where accuracy is important, careful considera-
tion of the power supply and ground return layout helps to
ensure the rated performance. The AD5301/AD5311/AD5321
should be decoupled to GND with 10 μF in parallel with a
0.1 μF capacitor, located as close to the package as possible.
The 10 μF capacitor should be the tantalum bead type, while

a ceramic 0.1 μF capacitor provides a sufficient low impedance
path to ground at high frequencies. The power supply lines of
the AD5301/AD5311/AD5321 should use as large a trace as
possible to provide low impedance paths. A ground line routed
between the SDA and SCL lines helps reduce crosstalk between
them. This is not required on a multilayer board as there is a
ground plane layer, but separating the lines helps.
