... The input stage is the headroom limit for signals approaching the positive rail. Figure 40 shows a typical offset voltage vs. the input common-mode voltage for the ADA4851-1/ADA4851-2/ ADA4851-4 amplifiers on a ±5 V supply. Accurate dc performance is maintained from approximately 200 mV below the negative supply to within 2 the positive supply. For high speed signals, however, there are other considerations. Figure 41 shows − ...

... OVERLOAD BEHAVIOR AND RECOVERY Input The specified input common-mode voltage of the ADA4851-1/ ADA4851-2/ADA4851-4 is 200 mV below the negative supply to within 2 the positive supply. Exceeding the top limit results in lower bandwidth and increased rise time, as shown in Figure 41 and Figure 42. Pushing the input voltage of a unity- gain follower to less than 2 V from the positive supply leads to the behavior shown in Figure 43— ...
