voltage is greater than ꢀHI and does not switch low again until  
the input voltage is less than ꢀLO, as given in Equation 2.  
USING HYSTERESIS  
Hysteresis can easily be added to a comparator through the  
addition of positive feedback. Adding hysteresis to a comparator  
offers an advantage in noisy environments where it is not desirable  
for the output to toggle between states when the input signal is  
near the switching threshold. Figure 17 shows a method for  
configuring the AD8564 with hysteresis.

where V+ is the positive supply voltage.  
The CF capacitor may also be added to introduce a pole into  
the feedback network. This has the effect of increasing the  
amount of hysteresis at high frequencies. This can be useful  
when comparing a relatively slow signal in a high frequency  
noise environment.

The input signal is connected directly to the inverting input of  
the comparator. The output is fed back to the noninverting  
input through R2 and R1. The ratio of R1 to R1 + R2 and the  
output swing establishes the width of the hysteresis window,  
with ꢀREF setting the center of the window or the average  
switching voltage. The output switches high when the input

At frequencies less than fP, the threshold voltages remain as it is  
in Equation 1.
