Equivalent Circuit
Positive digital supply pin for the ADC16061’s output drivers. This
pin should be connected to a +3V to +5V source and bypassed to
DGND I/O with a 0.1 µF monolithic capacitor. If the supply for this
pin is different from the supply used for V
be bypassed with a 10 µF capacitor. All bypass capacitors should
be located within 1 cm of the supply pin.
The ground return for the digital supply for the ADC16061’s output
drivers. This pin should be connected to the system digital ground,
but not be connected in close proximity to the ADC16061’s DGND
or AGND pins. See Section 5.0 (Layout and Grounding) for more
details.
All pins marked NC (no connect) should be left floating. Do not
connect the NC pins to ground, power supplies, or any other
potential or signal. These pins are used for test in the
manufacturing process.
