AD8676 Current limiting resistor

Hi,

I have three question about AD8676 Current Limiting resistor.

#1  Is there Internal protective circuit in AD8676?

      (for example, Protection diode)

#2  Is the input current limiting resistor necessary?

   (for examnple, IN a case beyond the differential input voltage"±0.7V")

#3  When limit resistance is necessary, how much "mA" is it necessary to set a limit to?

regards,

yuya

  • Hi,

    I found that AD797 and AD8622 mention the current limit for protecting differential input voltage.

    For AD797, it says that external resister is necessary.

    On the other hand AD8622 has internal resister(500ohm).

    Does AD8676 has inside protection resisters and what is the current limit ?
