    Hi Charles,

    My apologies for the delay. We were out of office on holiday. 

    You absolutely should not connect your circuit like this. The two LDC devices will try to independently drive the sensor. At best your inductive sensing data will be inaccurate and at worst you could damage the devices. You must use separate LC tanks for each LDC device.

    In addition, the LDC1000 is an older device that we do not recommend using for new designs. Please see the LDC Device Selection Guide for a list of newer inductive sensing devices that will work for you application.

    Best Regards,
