Hi Team,
Do we have any input/output capacitance vs Temperature data for the TS12A12511?
Thanks!

Hello Nabeel,
Thank you for your question.
Unfortunately, after reviewing the char data, it looks like the input/output capacitance spec was not taken over temperature.
May I ask why you like to know this information? Perhaps I can help you get different information that can be helpful.
Best regards,
Jared
I've got more information about this.
"I’m staking up a few of these in series as part of an impedance measurement using a 100kHz test signal, but their input/output capacitance has a typical spec of 60pF. I’ve got a way I can compensate/calibrate the measurements, but I want to know how much this capacitance can change over our operating temp (0 to 50 is fine)."
Any other thoughts for this circuit?
Hi Mike,
How are you using the capacitance in your measurements? What kind of compensation/calibration are you talking about?
Regards,
Jared
The capacitance isn't used or desired. We compensate by switching in known resistance values before and after the measurements and are doing a radiometric measurement vs an absolute measurement, so we can compensate/calibrate out non-idealities in the measurement.
Hello Mike,
If the capacitance isn't used in your impedance test, what value does it add to know how capacitance changes over temp? I am just trying to understand, in more detail, what you are trying to get at.
Regards,
Jared
