All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...
The OPA365 rail-to-rail input amplifier achieves rail-to-rail input swings using a charge pump to create a higher internal voltage for the input stage; in contrast to the more common method of using a ...
Input crossover distortion has long been the bane of rail-to-rail op amps. The input stage for most R-R amps consists of p-and n-channel differential pairs (Fig. 1a). The result is that the stage's ...
