Hi,

do you see any issue mulitplexing 2 coils to one LDC10xx and switching just one input - INA or INB - while keeping the other connected to both coils. ?

Many thanks,

Katharina

Hi,

It can be done, but the risk of picking up EMI noise from the inactive coil is greater. To reduce the environmental noise picking up, the traces should be as short an possible.

Best regards,

Don
