  • INA818: Differential Input Voltage

    TI Thinks Resolved
    Part Number: INA818 The datasheet of INA818 discribes two equations, G=1 + 50k/Rg and Vo=G*(Vin- - Vin+). When I select Rg=239, G=1 + 50k/239 = about 26 and Vo=26*(Vin- - Vin+). Then, when I measured Vo in Vin-=-0.3 and Vin+=4.7 (Vdiff=-5.0 V), this actual…
