It mentions parameters to be reviewed including the gain-bandwidth product, supply voltage and slew rate as well as the input common-mode range. It also notes the appearance of undesirable signal at the output of the op amp that could be due to the input common-mode-range and the impact ...
A common definition of input common mode voltage range (CMVR) that is used for Operational Amplifiers (Op-Amps) is the average voltage of the inverting and non-inverting input voltages. This is acceptable for an Op-Amp because they use negative feed...

The common-mode input signal rejection ratio (CMRR) of a differential amplifier is a metric used to indicate its ability to reject two signals or noises (common-mode noise) that have the same amplitude and phase at VIN(-) and VIN(+). It is expressed by t

If the input signals of an op-amp are outside the specified common-mode input voltage range, the gain of the differential amplifier decreases, resulting in a distortion of the output signal. If the input voltage is even higher and exceeds the maximum rat...

COMMON MODE RANGE OF BOOSTED IA The common-mode input range of the boosted IA is limited by the subregulated supply voltage. The outputs of the subregulator amplifiers, A6 and A7 must swing the common- mode voltage plus the subregulator voltage. The smaller the subregulator voltage, the ...
