Powering the Device
ESD Protection Diode Turn-On During Power-Up and
Power-Down
A particular power-up and power-down sequence must
be used to prevent any ESD diode from turning on
inadvertently. The figure above describes the sequence.
In general, AVDD and DVDD should power-up and
powerdown together to prevent ESD diodes from
turning on inadvertently. During this period, no voltage
should be applied to the IO’s for the same reason.

Ground Connection
AGND and DGND must both be set to 0V and preferably
star-connected to a central power source as shown in
the application diagram. A potential difference between
AGND and DGND may cause the ESD diodes to turn on
inadvertently.
