Description
5, 10 V
D
Positive digital supply pins. These pins should be
connected to a clean, quiet voltage source of +5V. V
A
and V
D
should have a common supply and be
separately bypassed with 10µF to 50µF capacitors in
parallel with 0.1µF capacitors.
12, 21 V
D
I/O
Positive supply pins for the digital output drivers.
These pins should be connected to a clean, quiet
voltage source of +3V to +5V and be separately
bypassed with 10µF capacitors.

AGND
The ground return for the analog supply. AGND and
DGND should be connected together close to the
ADC10321 package.
6, 11 DGND
The ground return for the digital supply. AGND and
DGND should be connected together close to the
ADC10321 pacjage.
13, 20 DGND I/O The ground return of the digital output drivers.
