1 If the reference input voltage is likely to exceed VDD by more than 0.3 V (for

example, during power-up) and the reference is capable of supplying 30 mA

or more, it is recommended to use a clamping diode between the REFIN pin

and the VDD pin. Figure 5 shows how the diode should be connected.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
