ADCMP533

bradstew on May 13, 2020

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.

Hi,

You can check ADCMP567 datasheet on how to implement additional hysteresis for high speed, ECL output comparators.

Try to look at page 10 and on page 11 Figures 9 and 10 for ideas that could possibly do the trick for you.

Thanks. I could work, but the ADCMP553 has a limit of 1.3V on +IN or -IN (Vcc-2V). So I'll need to experiment.
