LAYOUT CONSIDERATIONS
For the best performance, the following layout guidelines
should be observed. Always provide the analog power supply
(AVDD) and the digital power supply (DVDD) on separate
supplies, even if just from two different voltage regulators
driven by a common supply. Likewise, the ground connections
(AGND, DGND) should be kept separate as far back to the
source as possible (for example, separate the ground planes on a
localized board, even if the grounds connect to a common point
in the system). Bypass capacitors should be placed as close to
the supply pin as possible. Usually, a multitiered bypassing
scheme consisting of a small high frequency capacitor (100 pF)
placed close to the supply pin and progressively larger capacitors
(0.1 µF, 10 µF) placed further away from the actual supply source
works best.
