Description
16–20,
23–27
D0–D9
Digital output data. D0 is the LSB and D9 is the MSB of the
binary output word.
ANALOG POWER
2, 9, 10
V
DDA
Positive analog supply pins. These pins should be connected
to a quiet 3.0V source and bypassed to analog ground with a
0.1 μF monolithic capacitor located within 1 cm of these pins.
A 4.7 μF capacitor should also be used in parallel.
Ground return for the analog supply.

DDIO
Positive digital supply pins for the ADC10080’s output drivers.
This pin should be bypassed to digital ground with a 0.1 μF
monolithic capacitor located within 1 cm of this pin. A 4.7 μF
capacitor should also be used in parallel. The voltage on this
pin should never exceed the voltage on V
DDA
by more than
300 mV.
The ground return for the digital supply for the output drivers.
This pin should be connected to the digital ground, but not
near the analog ground.
