(1)

The analog inputs are protected as shown below. Input voltage magnitudes beyond the supply rails will not damage the device, provided

the current is limited per Absolute Maximum Ratings, Note 4. However, input errors will be generated If the input goes above VA and

below AGND.

(2)

Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of product characterization. The typical

specifications are not ensured.
