STRESS RATINGS

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

PACKAGE THERMAL PERFORMANCE

To reduce power consumption when using the part the user is

advised to turn off any unused ADCs .

The junction temperature must always stay below the

equation shows how to calculate the junction temperature:

where:

(DVDDIO × IDVDDIO) + (PVDD × IPVDD)).

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the

human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
