The Common-Mode Rejection Ratio (CMRR) of an opamp indicates its ability as a differential amplifier to suppress signals common (noise or unwanted signals) to its two inputs. In this EEFAQ, we will discuss this very important specification of an opamp and see what are the benefits of having a high…

COMMON-MODE REJECTION RATIO (CMRR) If a signal is applied equally to both inputs of an op amp, so that the differential input voltage is unaffected, the output should not be affected. In practice, changes in common mode voltage will produce changes in output. The op amp common-mode rejection ratio (CMRR) is the ratio of the

So then what is CMRR? The technical definition is the ratio of differential gain to common mode gain, but this doesn’t tell us much for a practical application. The common-mode input voltage affects the bias point of the input differential pair.
Common mode rejection ratio (CMMR) in audio. - Victory ...
https://givemebass.com/cmmr-in-audio/
Common mode rejection ratio is the ability for a device to reject or suppress “common mode noise” -that is noise that is common (identical) to both differential input channels. Let’s take an opamp for example with an audio signal at its differential (inverting and non inverting) inputs. Since a differential amplifier amplifies the difference between the two signals, even if it’s …
