We use ADCMP552 to do signal level judgment, result as follows:
At supply voltage = 3.3V, output high level =2.4V ; low level = 1.6V
At supply voltage = 5.0V, output high level =3.9V ; low level = 2.9V
But we want the gap of ADCMP552 output…
Just for a confirmation on differential Positive supply of ADCMP552/1, which states Vcco-Vcci min is -0.2V is this correct .
Which means that Output should be greater than input and should meet the min -0.2V . Is this right .
As i see for other…
Could you tell me about an ADCMP552 without hysteresis operation?
Can the ADCMP552 operate with a hysteresis pin connected to GND through 100k Ohm?
It's my mistake that the hys pin is connected to GND instead of Vcci.

Is there a way I can add some hysteresis to a ADCMP553 using external resistors like with a standard comparator? I would prefer this to a ADCMP552.
In the first page of LT1721 show clear that delay is 4.5ns. So, it is not suitable for your application.
If you only want to test the wave form (because you don't mention to rise/fall time & duty), you can you ADI higher speed comparator to generate…
