    Resolved
    Hi Dale, Thank you very much for your strong supports. I will tell the suggestions to the customer. It is very helpful for them and me. Could I ask you a request? Could you please consider modifying the current ADS8699 datasheet(SBAS777B) to clear RVS…

  • ADS8699: Long Term drift figures for the internal reference

    TI Thinks Resolved
    Part Number: ADS8699 Hi, regarding the internal reference of the ADC I do find some drift figures. However I am primarley interested in the long term drift of the internal reference. Does TI provide any figures regarding this topic? I am working on a…

  • ADS8699: random reading spikes

    Part Number: ADS8699 I'm getting semi-repeatable voltage conversions on a 9v battery. I don't think a battery should be this noisy (note the 9333 mV reading). I'm at the point where I don't have an idea of where the problem might be (program or electronics…

  • ADS8699: binary conversion to a voltage

    Part Number: ADS8699 Other Parts Discussed in Thread: ADS8691 Hi. We are testing out an ADS8699 ADC and I have two questions: My understanding is that if one uses the default values for range, etc., one should be able to read out the ADC values at +/…

  • RE: CCS/ADS8699: ADS8699 SPI DMA example c code

    Hello user5841294, After power up the ADC, all bits in DATAOUT_CTL_REG register are zero, the 32-bit output data on SDO-x will only include 18-bit conversion result and the rest bits will be all zeros, so you got right information on SDO-x. The default…
