Op Amp input protection
100Vdc could fuse open Rovp if it is not rated for 2W.

100Vdc could damage LDO's.  


Most LDO's are emitter followers, so they source but not sink or pull down.
Thus it could try to use the 100Vdc input to pullup Vcc to 85V or damage the LDO, so a CA type TVS is recommended on input or as OVP protection to protect supply.


This Op Amp has input pins with clamp diodes to the power supply pins and to each
other. Limit the input current to 10 mA or less whenever input signals
exceed the power supply rail by 0.3 V.

This Op Amp is CMOS so all precautions to prevent sensor or input/output voltage pullup before Op Amp power is applied must be done.

It is somewhat rugged with 6kV finger ESD protection as long as above precautions are added if expected.
