LTC2508

 Hi, I was wondering if I have a 30mA current getting into the In+ of LTC2508 in a long period of time, e.g. three months, would LTC2508 features be affected in anyways? e.g. the dynamic range?

    The only way to inject 30mA into the In+ input is by exceeding the absolute maximum rating for In+. The data sheet clearly states that exposure to any absolute max rating condition for extended periods may affect device reliability and lifetime.

    " The only way to inject 30mA into the In+ input is by exceeding the absolute maximum rating for In+" is it because the absolute maximum for Analog Input Leakage Current is 10nA or because the absolute maximum for Digital Input Current is 10uA?

    your statement is absolutely right according to Note.1, on the other hand, Note.3. says "This product can handle input currents up to 100mA below ground or above REF or OVDD without latch-up".
