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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
Specifications to T

= -40°C are guaranteed by design, not production tested.
Note 2:
Measurements at high current are pulse tested, such that the junction temperature is ambient temperature. Minimum supply
voltage for output accuracy must be at least 1.425V.
