Original question:

TLV7031: TLV7031 Output is incorrect

TLV7031: 31mV low reference voltage comparator

Part Number: TLV7031

Hey there,

I'm using TLV7031 as a low reference voltage comparator, as the reference voltage is just 31mV. I added some hysteresis for about 31mV/19mV thresholds. I think TLV7031 can support that, and the only interferer source is the offset voltage which can go up to +-8mV.

    Hi, 

    Thank you for your post. I would like to know more about your question and about your use for the part. Are you implementing external hysteresis in addition to the TLV7031's internal hysteresis of 7mV? If you set the reference voltage to 31mV, then the thresholds (with the internal hysteresis) will be VH=34.5mV and VL=27.5mV. 

    What is your input signal in your circuit and what is your desired output? 

    Thanks,

    Joe
