    Hi Clemens, You can still use the COM layer. Just add the shunt capacitors and the common-mode choke as close to the COM pin as possible. Figure 33 in the LDC2114 datasheet shows an example layout. You can use Ccom as one of the recommended shunt capacitors…

  • RE: LDC2114: How to implement passive filters with LDC2114?

    Resolved
    Both options should help. Option 1 will help the most; however, it requires more components than option 2. I recommend going with option 1. If your tests pass, then you can always remove the extra capacitors on the INx signals and retest.

  • RE: LDC2114: Using multiple LDC2114

    Resolved
    Hello Clemens, My apologies for not responding earlier. Yes, only muxing the SDA will work. If the part sees SCLK pulses without its address, it will ignore the I2C communications. Regards, ChrisO

    Resolved
    Hello, I'm very sorry for my late response. You're right, we just put the chokes in the IN-lines without changing sensor parameters. Later we'll go in here deeper to determine the parameters. Meanwhile we were measuring our system in an EMC…

    Part Number: LDC2114 Hello, When I reconnect LDC2114 EVM to PC, GUI loads the previous configuration of registers. Does LDC store the configured register value? Will it reset to default value when power off? Thank you.
