Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is

functional but do not guarantee specific performance limits For guaranteed specifications and test conditions see the Electrical Characteristics The guaranteed

specifications apply only for the test conditions listed Some performance characteristics may degrade when the device is not operated under the listed test

conditions

Note 2

All voltages are measured with respect to AGND and DGND unless otherwise specified

Note 3
