Understanding the ADA4091-4 Input protection circuitry

I have a circuit design which has an op amp with +/-15V rails feeding into an ADA4091-4 on 0->3.3V. There is 9.4k between the 2 parts of the circuit. Is this sufficient to protect the 4091 in light of an over voltage condition, or will it fail immediately or over time? I have been reading app notes on the input circuitry, and I am currently interpreting its main purpose to be for ESD protection.
