LDC1614EVM: LDC1614EVM

Part Number: LDC1614EVM
Other Parts Discussed in Thread: LDC1614

Hello

I am using LDC1614 EVM and connected Coil to it and measurements are good as expected. My Question is How can I use 32 Coils through Multiplexer?

My current configuration is that I am using ADG732 32 to 1 Multiplexer, but output is really distorted.

is it possible to measure inductance through any other kind of multiplexer?

Thanks

Kamal

    Hi Kamal,
    Please avoid "hot-swaps" meaning you should not change the sensor connections while the LDC is actively driving the sensor. This would corrupt the measured data. If you've to use a multiplexer, try putting the LDC into sleep mode before changing the connections, which ensures that none of the sensors will be driven. However, we recommend using multiple LDC devices with a dedicated channel for each sensor instead of a multiplexer.
