Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. Measured with respect to AGND with REF – and GND wired together (unless otherwise noted).
2. Measured with respect to DGND.

NOTES:
3. The absolute difference between AVDD, BDVDD and DVDD should be less than 0.5 V.
4. Analog input voltages greater than that applied to VREFP convert as all ones (111111111111), while input voltages less than that
applied to VREFM convert as all zeros (000000000000).
