MT-041 TUTORIAL Op Amp Input and Output Common-Mode and Differential Voltage Range INPUT AND OUTPUT VOLTAGE RANGE Some practical basic points are now considered regarding the allowable input and output voltage ranges of a real op amp. This obviously varies with not only the specific device, but...
) of an op-amp? The common-mode input voltage (CMVIN) is defined in the electrical characteristics of the operational amplifier datasheet. This characteristic is input voltage that satisfies the electrical characteristics (CMRR, etc.) of the data sheet when ...

If you really do want a x3 amp run off 0V and +12V then you cannot have an input voltage of more than 4V if you assume that the opamp output voltage can really reach the +12V rail. In practice that will not be possible: it will be below that by somewhere between a few mV and ...
Whenever an op amp input common mode (CM) voltage goes outside its supply range, the op amp can be damaged, even if the supplies are turned off. Accordingly, the absolute maximum input ratings of almost all op amps limits the greatest applied voltage to a level equal to the positive and...
