6.3.2 Common-Mode Rejection Ratio

The common-mode rejection ratio (CMRR) of an amplifier is a measure of how well the device rejects unwanted input signals common to both input leads. The CMRR is found by taking the ratio of the change in input offset voltage to the change in the input voltage, then converting the ratio to decibels. Ideally the CMRR is infinite, but in practice, amplifiers are designed to have the CMRR as high as possible. The CMRR of the RC4558 device is 94dB.
