LDC1101: LDC1101

Part Number: LDC1101

 VDD is powered from 3.3V digital and ground and the Rp values are excessively noisy. Don't have the common mode filter laid out on the board, so I only have the two 0402 EMI caps on the INA/INB pins to ground to mitigate EMI susceptibility. Would the noise be less if I run the sensor IC from a 1.8V LDO like on the EVM board?

  • Hello, 

    You should be able to get a clean result with the VDD at either voltage. What are you using for a sample rate in this application? If you increase the RESP_TIME setting, do you see better results? 

    Best Regards,
