Equivalent Circuit

Description

Digital supply pin. This pin should be connected to a quiet

voltage source of +3.0V to +3.6V. V

A and VD 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

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,

AGND

The ground return for the analog supply. AGND and DGND

should be connected together close to the ADC10D040

package.

DGND

The ground return for the digital supply. AGND and DGND

should be connected together close to the ADC10D040

package.
