    Part Number: ADS1120-Q1 Hey Matt. Its been long while .. What's up.. How are you ?? I have been using the ADS1120-Q1 for my current measurement . I have tried with the two different register 2 configuration. One with the VREF as : Analog supply (AVDD…

  • ADS1120-Q1: ADS1120-Q1 Communication: Read back data is always 0xFF

    Part Number: ADS1120-Q1 Hello I have been using ADS1120-Q1 for reading an analog voltage on the IN0 pin vs AVSS (IN1,IN2,IN3,REFN0,REFP0,DRDY are left unused & VA is fed 5V & CLK pin is tied to GND) & the configuration registers are set as below:…

  • ADS1120: Intermittent fault connects AIN1 pin to VSS - could the device be faulty?

    TI Thinks Resolved
    Part Number: ADS1120 We have a sensor gateway that is normally mounted in an industrial environment. This gateway samples a PT100 sensor value ever so often, and a few gateways will sometimes register a value way out of its normal range. This will come…
