FDC2214: The difference between FDC2214 and FR2633

Part Number: FDC2214

Dear Experts

Could you identify the difference between FDC2214 and FR2633?

Is seems the price of FR2633 is lower than FDC2214.

What is the concern to use FR2633 to replace FDC2214?

My customer purchased a FDC2214EVM and try the proximity sensing.

It can detect around 3~4cm instead of about 10cm described in the user guide.

So what is the longest distance that FDC2214EVM can detect?

Thanks for your comment.

  • Hi Jefferey,

    Please ask your customer to tape down the EVM and USB cable while testing to minimize mechanical interference.

    Also, unplug the power cord of the laptop which can inject noise and interference. 

    With proper setup, the noise floor of the EVM should be a few fF. The Captivate solution has lower resolution and shorter range. 

    Regards,
