CROSSOVER BIAS POINT  
Rail-to-rail inputs of this type, in both op amps and comparators,  
have a dual front-end design. Certain devices are active near the  
INPUT VOLTAGE  
VCC rail and others are active near the VEE rail or ground. At some  
V
± V  
OS  
predetermined point in the common-mode range, a crossover  
occurs. At this point, normally VCC/2, the direction of the bias  
current reverses, and there are changes in measured offset  
voltages and currents.

DISPERSION  
Q OUTPUT  
The AD8468 slightly elaborates on this scheme. Crossover  
points can be found at approximately 0.8 V and 1.6 V.

MINIMUM INPUT SLEW RATE REQUIREMENT  
INPUT VOLTAGE  
1V/ns  
With the rated load capacitance and normal good PC board  
design practice, as discussed in the Optimizing Performance  
section, these comparators should be stable at any input slew  
rate with no hysteresis. Broadband noise from the input stage is  
observed in place of the violent chattering seen with most other  
high speed comparators. With additional capacitive loading or  
poor bypassing, oscillation may be encountered. These oscilla-  
tions are due to the high gain bandwidth of the comparator in  
combination with feedback through parasitics in the package  
and PC board. In many applications, chattering is not harmful.
