  • INA191: Enable voltage requirement

    TI Thinks Resolved
    Part Number: INA191 Hello, The VIH for the enable pin of INA191 is listed as 1.35V min and 5.5V max. Does EN need to be the same as VS? FOr example, could we use 1.5V as the enable voltage with 5.5V supply? Thanks, Michael

  • RE: SHUNT_VOLTAGE_REFERENCE_RESISTOR_CALCULATOR: Current measurement on HV power supplies

    Hi, The concept works. GREF1 however can’t be truly floating, it must be referenced to somewhere below 30kV. The uA range current is too small for INA271 to measure. Because the input bias current is on the same order. The model is likely not very…
