Other Parts Discussed in Thread: FDC2114
Hi,
we are trying to interface TI’s FDC2112 with one of our products.
We tried configuring the IC as per the datasheet and were unable to see any result. We are able to read the Device ID properly.
We also referred a spreadsheet available on the TI site after referring TI blogs on issues with FDC2x1x ICs and discrepancies in the datasheet.
The calculations as per the spreadsheet are different from that mentioned in the datasheet.
Even the spreadsheet configurations didn’t help.
Can you please help with the complete register settings for below sensor configuration:
C = 22pf
L = 9.4uH
Parasitic capacitance = 20pf
Sensor capacitance range: 0pf-40pf
Single channel configuration (Ch0).
Sample rate: 1sps is OK for us.
Internal oscillator as source for Fref.
Thanks and Best Regards,
