  • RE: ADS1222: ADS1222 always returns value of 0x00

    Hi Tony, Tony said: I could receive ADC value about +- 22900 (X) at no load. The value varied X-- for one way and X++ for the other way. Is this proper behavior. This feels like a lot of variation, but it's probably because you have such a large gain in…

  • Issues in ADS1222 ( not giving proper out values)

    Resolved
    Other Parts Discussed in Thread: ADS1222 Why out put of ADS1222 is drifting drastically. if we read continuously from the ADC the ADC o/p values are too much varying. there no such variations in analog input. Giving Vref as vdd 0550.ads1222.doc Vcc
