ADCMP601 hysteresis vs. common mode voltage

Category: Hardware
Product Number: ADCMP601

 In Figure 20 of the datasheet, the hysteresis is shown around 0V input common mode voltage.  Does this plot apply with a 2.5V input common mode voltage?  In other words, is the hysteresis independent of the input common mode voltage?

Thanks,

  • Hello,

    The hysteresis response is dependent on the threshold voltage (in most case, the voltage reference on the inverting input).
    The graph in Figure 20 is in 0V because in the example, the threshold voltage was set to 0V.


    For example, if the threshold voltage was set to 1V, then V L->H = 1V + (VH/2) and V H->L = 1V - (VH/2)
    Hope it helped.
