POWER SUPPLIES
Three supplies are used on the ADS1601: analog (AVDD),
digital (DVDD) and digital I/O (IOVDD). Each supply must
be suitably bypassed to achieve the best performance. It
is recommended that a 1
μ
F and 0.1
μ
F ceramic capacitor
be placed as close to each supply pin as possible. Connect
each supply-pin bypass capacitor to the associated
ground, as shown in Figure 50. Each main supply bus
should also be bypassed with a bank of capacitors from
47
μ
F to 0.1
μ
F, as shown.
The I/O and digital supplies (IOVDD and DVDD) can be
connected together when using the same voltage. In this
case, only one bank of 47
μ
F to 0.1
μ
F capacitors is needed
on the main supply bus, though each supply pin must still
be bypassed with a 1
μ
F and 0.1
μ
F ceramic capacitor.
