Hi,
Good Day. I have a customer who is working with FDC2212. Please see below his query for your reference. Thank you very much.
Kindly provide the details on drift in capacitance measurement due to following: 1) Effect of 3.3v variation on Frequency measurement % 2) Effect of ambient temperature on Frequency measurement in terms of % 3) In the given illustrated example in data sheet page 42 Freq calculated is 5.15Mhz , is it ok if we get 4.2 Mhz 4) Does the frequency of tank circuit depend on the register configuration settings or only the tank circuit L C 18uh - 33pf . We are using differential mode
Best Regards,
Ray Vincent
