LDC1612EVM: LDC1612EVM effect of external magnetic field

Stefan Schwertner

Part Number: LDC1612EVM

Hi,

does a external magnetic field (50kHz) effect the Sensor (2-3MHz)? Can the Effect be reduced by a filter inside the sensor-circuit ?

Best regards

Hi Stefan,

The LC tank is inherently a narrow bandpass filter, so the 50kHz magnetic field should not affect your sensor. You can verify this by measuring the frequency response of your LC tank and finding the -3dB points.
