  • LDC2112: the LDC2112 chip work as a simple digital sensor

    TI Thinks Resolved
    Part Number: LDC2112 Hi expert, Is there any recommended configuration to make the LDC2112 chip work as a simple digital sensor, in case it detects the presence or absence of a metal object? Thanks! Best regards Jiahui

  • RE: LDC2112: Voltage on SCL

    Resolved
    Hello Cameron, Using the LDC2114 would eliminate the LC_WD error from occurring on the other channel. Is there a reason they care about this error monitoring? Unless they are trying to use INTB in their application to check for the LC_WD status of the…

  • LDC2112: LDC2112 baseline tracking question

    TI Thinks Resolved
    Part Number: LDC2112 Hi TI, We use LDC2112 as touch button application. At beginning, our LP_BASE_INC(0x15) setting is b011(base on the LDC2112 config tool). How about if we set BINC like LP_BASE_INC to maximum as b111?Does it has other side effects…

  • LDC2112: LDC2112 raw data change with temperature at different FPC vendor

    Resolved
    Part Number: LDC2112 Hi We met a problem that when we put our DUT from ambient into freezer (~ 0 degree), some DUT LDC2112 raw data will change And we find it's because different FPC vendor (our LC coil pattern is on FPC) The FPC vendor CMI it's LDC2112…

  • LDC2112: LDC 2112 Ccom

    Resolved
    Part Number: LDC2112 Dear TI team, I have one question to the Ccom value. In your excel sheet I got a value Ccom min > 2.15 nF and Ccom max < 26.88 nF. Actually we are using a Ccom with a value of 2.2 nF. Is this to be seen critically? Furthermore…

  • LDC2112: LDC2112 EMI trace and coil shielding

    Part Number: LDC2112 Hi Since we have a issue that when our MCU IC internal power is DCDC mode(switching frequency is 8MHz), it radiation impact our LDC2112 coil(design resonant frequency is ~13MHz) that the LDC2112 base raw data become 100~200(when at…

  • RE: LDC2112: LDC2112 resonant frequency measure and -2048 mean

    Hello Poki, It seems like the change in the coil is causing the data to go to a max negative. If rebooting the system works, then it is a problem with the large mechanical change during the assembly. If you do not want to reboot the system, you can also…

  • LDC2112: LDC2112 raw data unstable since our MCU at DC-DC mode has switching radiation

    Part Number: LDC2112 Other Parts Discussed in Thread: FDC1004 Hi: Since when we don't touch the metal but when our MCU at DC-DC mode(it's switching frequency is 8MHz), because it has radiation, the LDC2112 raw data is unstable (when MCU at LDO mode, the…
