/blogs_/archives/b/precisionhub/posts/dealing-with-rejection-instrumentation-amplifier-psrr-and-cmrrElectrical engineers are accustomed to dealing with rejection, and we absolutely love it. From common-mode rejection to power supply rejection, and even EMI rejection. The more rejection, the better!
