Pin Descriptions and Equivalent Circuits
(Continued)
Pin No. Symbol Equivalent Circuit Description
4 V
D
Digital supply pin. This pin should be connected to a quiet
voltage source of +2.7V to +3.6V. V
A
and V
D
should have a
common supply and be separately bypassed with 10 µF to 50
µF capacitors in parallel with 0.1 µF capacitors.
6, 30 V
DR
Digital output driver supply pins. These pins should be
connected to a voltage source of +1.5V to V
D
and be
bypassed with 10 µF to 50 µF capacitors in parallel with 0.1
µF capacitors.
3, 39, 42,
46
AGND
The ground return for the analog supply. AGND and DGND
should be connected together close to the ADC10D020
package.
5 DGND
The ground return for the digital supply. AGND and DGND
should be connected together close to the ADC10D020
package.
7, 29 DR GND The ground return of the digital output drivers.
