ADCMP380 Datasheet mentions Vref = 0.6V in the section "Adding Hysteresis". Is this correct?

Hi Analog

I have a short question on the ADCMP380 datasheet (Rev A).

On page 8 in the section "Adding Hysteresis" Vref is said to be 0.6V (in the right column about in the middle). Is this this correct and this is a different internal reference voltage that the 1V or 0.5V input comparison voltage?

Best regards

    Hello Thomas,

    The Vref should be either 0.5V or 1V, based on the version of ADCMP380 you are using.

    If you are using the scheme in the datasheet to add hysteresis, make sure you scale R1, R2 and Rpull-up accordingly, so that you do not exceed the maximum sink current capability of the OUT pin, and you are driving a high impedance pin.
