ommended to be bypassed to system ground using
0.1 µF X7R type capacitors.
The VA- supply is connected to the CMOS sub-
strate and as such must remain the most negative
applied voltage to prevent potential latch-up condi-
tions. Care should be taken to ensure analog input
voltages do not drop more than -0.3 V below the
VA- supply. Care should also be taken to establish
the VA- supply before analog signals are applied to
the device. It is recommended to clamp the VA-
supply to system ground using a reversed biased
Schottky diode to prevent possible latch-up condi-
tions related to mismatched supply rail initializa-
tion.
2.3.2 Digital Power Supplies
The digital power supply across the VD and DGND
pins is flexible and can be set to interface with 3.3V
or 5V logic. The digital power supply should be by-
passed to system ground using a 0.01 µF X7R type
capacitor.
