Other Parts Discussed in Thread: LDC1314

Hi

What kind of impact is considerable if the electromagnetic wave is applied to LDC1314 sensor?

Is the impact insignificant if the electromagnetic wave is far away from sensor freq?

Bestregards

    Hello,
    The LDC1314 is a very narrowband resonsant sensor. If the frequency of the electromagentic wave is very close to the fundamental frequency then it may show up. However if it falls outside of this range there is inherent filtering in place due to the LC parallel tank acting as a narrowband bandpass filter. If you can increase the Q of the circuit, this will help improve the immunity. However, for any specific configuration we suggest prototyping the circuit and collecting the raw data.
