Over voltage protection input of AD8610?

I fully understand Input overvoltage protection for the amplifier (page 16).

example

Let us AD8610 , PS +- 16V, on + input serial protective resitor 100k.

What maximum non destrucitve voltage on +input AD8610?

  • I'm sorry, 16V is a typo, the power supply is +-13V.

    The essence of the query is Input Over voltage protection, on Page 16 DS.

    You say 10k Ohm resistor add 5V , but Georg Simon Ohm law say 5mA over 10k resistor need 50V.

    It 5V misprint or OVP calculate somehow mysteriously?

    When we discuss the already AD8610.

    Input Offset Voltage Adjustment,this topic is also rather DS only indicated.

    There are some more details on null input?

    Considered in the design of dynamic compensation Input Offset Voltage ( by DAC) and because the input resistance, I would like to avoid the connection to -IN, +IN input
