    Thread Summary
    
                The user inquired about the potential impact of atmospheric pressure on the ADG441BRZ and AD7843 parts when used at altitudes between 1000m and 3000m. The support engineer confirmed no known issues at these altitudes and asked if the user was trying to meet a specific JEDEC or Industrial standard. The user's customer was satisfied with this response.

    My customers want to use parts(ADG441BRZ) 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 AD7843.
