ADA4638-1

Hi,

I have to buffering a signal, derived from an AD8226 INAMP, using an opamp like the ADA4638-1.

The INAMP is powered with +12V, while the opamp uses +3.3V because it's interfaced with an ADC that works in the range 0:3V.

in the following table are summarized the absolute maximum ratings of the ADA4638-1:

In order to protect the opamp it's enough to mantain the input current within the specified value (10mA) or I also need to protect the input against the overvoltage?

To avoid a permanently damage on the internal protection diodes it's enough limit the input current, even if the input voltage could be 12V ?

Thanks in advance
