  • RE: ADS112U04: ADS112U04 : reads low thermocouple voltage

    Resolved
    Thanks Bob. I just got to know the microcontroller which I'm using operates in the –40 to +105 °C temperature range, so now it doesn't matter how ADS112U04/LM94022 behaves below -40°C as micro functioning is not guaranteed at this temperature…

  • ADS112U04: Measuring AC Main Voltage

    TI Thinks Resolved
    Part Number: ADS112U04 Other Parts Discussed in Thread: AMC1100 , AMC3330 Hi team, I'm trying to measure 50/60 Hz AC main voltage with ADS112U04. AMC1100 should be used for isolated amp. I think 2kSPS is enough for measurement. UART communication feature…
