Pin Descriptions and Equivalent Circuits (Continued)

Digital Power

Positive digital supply pin. This pin should be connected to the

same clean, quiet +5V source as is V

A and bypassed to DGND

with a 0.1 µF monolithic capacitor in parallel with a 10µF capacitor,

both located within 1 cm of the power pin.

DGND

The ground return for the digital supply. AGND and DGND should

be connected together directly beneath the ADC16061 package.

See Section 5 (Layout and Grounding) for more details.

D I/O

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

A and VD, it should also

be bypassed with a 10 µF capacitor. All bypass capacitors should

be located within 1 cm of the supply pin.

DGND I/O

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.
