Other Parts Discussed in Thread: LDC3114
Dear ladies and gentlemen,
I have a question concerning the EMC and ESD protection needed for the LDC3114: In the evaluation board as well as in the datasheet, you do not show any safety circuits against ESD and EMC in case of an external inductor (coil not on the same PCB as IC). What kind of circuit do you recommend in that case?
Usually, we use a low-capacitive varactor to GND together with a ceries capacitor to keep the ICs free from spikes and overvoltages. Does the IC need a DC path trough the inductor?
Thanks in advance,
