Note 7: All inputs are protected as shown below. Input voltage magnitudes up to 500 mV above the supply voltage or 500 mV below GND will not damage this

device. However, errors in the A/D conversion can occur if the input goes above V

or below AGND by more than 300 mV. As an example, if V

is 3.0 V

, the

full-scale input voltage must be ≤3.3 V

to ensure accurate conversions.

Note 8: To guarantee accuracy, it is required that V

and V

be well bypassed. Each V

and V

pin must be decoupled with separate bypass capacitors.

Note 9: Typical figures are at T

= 25˚C, and represent most likely parametric norms. Test limits are guaranteed to National’s AOQL (Average Outgoing Quality

Level).
