Keywords:electromagnetic interference  EMI  rejection ratio  EMIRR  operational amplifiers 

[Summary of tips] The electromagnetic interference (EMI) rejection ratio, or EMIRR, describes the EMI immunity of operational amplifiers. An adverse effect that is common to many op amps is a change in the offset voltage as a result of RF signal rectification. An op amp that is more efficient at rejecting this change in offset as a result of EMI......
