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:
2. The device operates over the supply voltage range of 2.7 V to 5.5 V. Over this voltage range the device responds correctly to data
input by changing the output voltage but conversion accuracy is not specified over this extended range.
3. This is specified by design but is not production tested.
