Positive analog supply pins. These pins should be connected to a
quiet +5V voltage source and bypassed to ground with 0.1 µF
monolithic capacitors located within 1 cm of these power pins, and
with a 10 µF capacitor.
The ground return for the analog supply.
Positive digital supply pin. This pin should be connected to the
same quiet +5V source as is V
µF monolithic capacitor in parallel with a 10 µF capacitor, both
located within 1 cm of the power pin.
The ground return for the digital supply.
Positive digital supply pin for the ADC12040's output drivers. This
pin should be connected to a voltage source of +2.35V to +5V and
be bypassed to DR GND with a 0.1 µF monolithic capacitor. If the
supply for this pin is different from the supply used for V
it should also be bypassed with a 10 µF tantalum capacitor. V
should never exceed the voltage on V
should be located within 1 cm of the supply pin.
The ground return for the digital supply for the ADC12040's output
drivers. This pin should be connected to the system ground, but
not be connected in close proximity to the ADC12040's DGND or
AGND pins. See Section 5 (Layout and Grounding) for more
details.
