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.
For voltages beyond these limits, use input protection resistors. See the
Theory of Operation section for more information.
There are ESD protection diodes from the reference input to each supply, so
REF cannot be driven beyond the supplies in the same way that +IN and −IN
can. See the Reference Terminal section for more information.
