FDC1004EVM: Connection for the conventional approach

Dante Uriel Ferreyra

Part Number: FDC1004EVM

Hello, I'm trying to apply the conventional approach to sense the liquid level of a container, but I'm a little confused on where to connect the level and reference sensors and their ground electrodes to the FDC1004EVM. Could you please tell me where should those electrodes be connected?

Thanks in advance.

Hello,

You can find diagrams for the conventional liquid level sensing approach in section 1 of this application note: http://www.ti.com/lit/an/snoa925/snoa925.pdf

All of the reference or level electrodes should be connected to CINx pins on the EVM and the GND electrodes should be connected to the local EVM GND. Either SHIELDx pin can be used.

Best Regards,
