  • INA240: Output offset

    Resolved
    Part Number: INA240 Hi, I am simulating the INA240A2 with LTSpice (or Tina TI gives the same results) and I have an output offset of 29mV when the input is connected to the GND. This offset is here when I have a current below 80mA in my schematic. I try…

  • INA240: How to calculate accuracy of INA series

    Resolved
    Part Number: INA240 Hi Expert, For current sensing, customer usually give a target current accuracy, for example 0.01%. If I only use ADC, the accuracy should be 1/2LSB(~14Bit ADC for 0.01%). I want to know, when I use a INA240+14Bit ADC, how to calculate…
