Other Parts Discussed in Thread: OPA657
Hello,
we wan't to model our signal chain as accurate as possible. Can you share the input capactitance of the TLV3702 and OPA657?
Thank you and best regards,
Ambroise

Hi Ambroise,
Thank you for your question. Typically, the input capacitance of the TLV3702 is less than 10 pF.
Since I am assuming this is not a fast application, I would recommend placing a 100 Ω or 1 kΩ resistor between the output of the op amp and the input of the TLV3702 if the OPA657 is driving the inputs of the comparator.
Are you driving an input of the TLV3702 with the output of the OPA657?
Best Regards,
