  • INA191: Enable voltage requirement

    Michael Balourdas

    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

    Hi Pedro, As you mentioned, 3-decade is a big range to cover with accuracy. It might be possible with a simple solution as proposed. The concern however is if the accuracy requirement can be satisfied at 1mA. INA4290 is a great choice, but I encourage…
