Thanks for your question. I would like to answer but this is quite challenging to measure. The TLV1701 can have input offset voltage in the 2mV range. So trying to predict the propagation delay at such a low overdrive would require zeroing out the offset first. Propagation delay is also impacted by underdrive voltage, so that would also need to be considered. Can you share more about your application? Do you need the extended operating voltage of the TLV1701? I am asking because some of our lower voltage comparators would probably have faster response times at such low overdrive.
Thank you for your reply.
My customer is considering TLV1701 and TLV3401.
Propagation delay = 500nsec @overdrive=100mV
Propagation delay=300usec ＠overdrive=2mV
Propagation delay=30usec ＠overdrive=50mV
Propagation delay=30usec ＠overdrive=100mV
Customer usecase for overdrive is 2mV.
Which device is higher response?
