AD7843 are used at mountains

My customers want to use parts(AD7843ARQZ) at high altitude.
Are parts affected by atmospheric pressure when parts are used at mountains with altitude 1000m to 3000m?
I read the Reliability Handbook(UG-311), but I could not find the corresponding article.
May I confirm it to be sure?

I also posted a similar question about the ADG444.

Best regards
