  • ADS124S08: ADS124S08 Floating Inputs Getting Error

    TI Thinks Resolved
    Part Number: ADS124S08 Tool/software: I used ADS124S08 in my design. When the input is connected to a known value, it gives the correct value. Although there is a pull down resistor connected to the input pins, it does not give '0' in the floating state…
