Notes:
1. Absolute Maximum Ratings are stress ratings only.
Permanent damage to the device may be caused by
continuously operating at or beyond these limits. De-
vice functional operating range limits are given under
Recommended Operating Conditions. Guaranteed
performance specifications are given under Electrical
Characteristics at the test conditions specified.
2. The device operates over the supply voltage range of
2.7V to 5.5V. Over this voltage range the device re-
sponds correctly to data input by changing the voltage
output but conversion accuracy is not specified over
this extended range.
