Hello,
In my prototype I want to measure at different sensor frequencies,
so I change the value of the capacitor to change the resonance frequency.
When I measure at 170 kHz the LDC1000 works correct,
but when I want to use a lower frequency like 47 kHz, the LDC1000 doesn't work correct.
Without any metal in the front of the coil it works correct, but when a metal object gets to close to the coil the LDC1000 stops.
When the metal object gets closer to the coil, the voltage on the CFB rises to 5V.
What would be the problem?
Kind regards,
Joris.
