LDC1612: Spikes in LDC1612 multichannel data despite correct deglitch settings

Sugan Shrestha

Part Number: LDC1612

Hi,

We have an LDC1612 set up in multi-channel read configuration and the frequencies for CH0 and CH1 are 1.6 Mhz and 2.4 Mhz respectively.

The internal deglitch filter is set to 3.3 MHz which according to the datasheet should be correct.

Despite these settings we keep seeing spikes (maybe saturated values) in the sensor recordings.

Has anyone had similar issues?

Hi Sugan,

Thank you for posting.

What is the approximate value of the spikes you are seeing? Additionally, are you able to re-upload the image to include the x and y axis values?

Best regards,

Nicole

Hi Nicole,

Thank you for the response.

The values are random and appeared even when a known constant value from RCOUNT registers were being read.

I found that it was the issue with the i2c driver code and not the ldc1612 and has been resolved.

Regards,

Sugan
