  • FDC2212-Q1: FDC2212-Q1

    Part Number: FDC2212-Q1 Other Parts Discussed in Thread: FDC1004 Tool/software: Hi John, about 3 months ago, you proposed the FDC1004 instead of the FDC2x1y with the following reasoning: "Also, many customers have struggled to get to production with…

  • RE: FDC2212-Q1: FDC2212-Q1

    Hello Jochen, I see the AEC-Q qualification listed in our FDC2212-Q1 datasheet: For this device, we have the FDC2212-Q1 that is qualified and we have the FDC2212 that is not AEC qualified. In general, our devices that are AEC qualified will have a "…

  • RE: FDC2212: Resonance Frequency

    Thanks for the clarification. Please let me know if you have additional questions after trying the single-ended configuration. Best regards, Jesse

  • FDC2212: Electric components in the middle of the sensor coil

    TI Thinks Resolved
    Part Number: FDC2212 Tool/software: Hello, we are currently developing a device, which emits light. To ensure that the light can't be directly emitted to the eyes, we wan't to use the FDC2212 to detect if something is covering the light source. To achieve…

  • FDC2212: Incorrect Sensor Tank Oscillation Patterns

    TI Thinks Resolved
    Part Number: FDC2212 Hi TI Team, I have probed the sensor channel 0 on the circuit with a digital logic analyzer to verify the oscillation of the sensor tank and I have encountered some uncertainties regarding the observed signals . Channel 1 displays…

  • FDC2212: Trouble reading and writing to the sensor using I2C protocol in Arduino Environment

    Resolved
    Part Number: FDC2212 Hi TI team, I am trying to program the FDC2212 sensor registers using the Teensy board and I am having difficulty with using I2C protocol to read/write from registers. I believe that the register address is 8bits and each register…

  • FDC2212: Some using problems

    TI Thinks Resolved
    Part Number: FDC2212 1 : Consistency problem. Currently we use FDC2212 two channels in single-ended mode, 10PCS board inside, the same conditions to collect the capacitance consistency is very poor. There will be a 2pf gap between different devices. But…

  • FDC2212: Configuring the sensor for high accuracy/precision, high speed applications

    TI Thinks Resolved
    Part Number: FDC2212 Hi team, We are working on a capacitive sensing project that requires very high accuracy. Ideally, we would like the sensor to be able to differentiate in steps less than 5fF as our entire sensing range is roughly 200fF. Will the…

  • FDC2212: incorrect acquisition data

    Part Number: FDC2212 Hello, One customer used FDC2212 for his application, but he found that the sampled data is incorrect. CH0_FIN_SEL=b10 CH0_FREF_DIVIDER =0x01 DRIVE_CURRENT_CH0=0xA800, INA0 Vpp=1.5V SETTLECOUNT register (0x10) is 0x000E. CH0_RCOUNT…
