NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the

device at these or any other conditions above those listed in the operational sections

of this specification is not implied. Exposure to absolute maximum rating condi-

tions for extended periods may affect device reliability.

2If the Reference Input Voltage is likely to exceed V

DD by more than 0.3 V (e.g.,

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 VDD pin. The

diagram below shows how the diode should be connected.
