No. Symbol Equivalent Circuit

Description

5, 10 V

Positive digital supply pins. These pins should be

connected to a clean, quiet voltage source of +5V. V

and V

should have a common supply and be

separately bypassed with 10µF to 50µF capacitors in

parallel with 0.1µF capacitors.

12, 21 V

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.

4, 27,

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.
