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
maximum junction temperature (T J MAX ) of 125°C. This
equation shows how to calculate the junction temperature:
T J = T A Max + (θ JA × W Max )
where:
T A Max = 85°C.
θ JA = 30°C/W.
W Max = (( AVDD × IAVDD ) + ( DVDD × IDVDD ) +
( 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.
