INA193A-Q1: about input bias current

Part Number: INA193A-Q1

Hi team

INA193A-Q1 D/S say Input bias current = Max 23uA at Vin- pin..

so total input bias current would be Max 46uA(= 23uA x 2) for two input pins ?

further, may I know total input bias current for  two input pins at Vs = 0V and common mode voltage = 20V ?

    Hello Paul,

    Thank you for your interest in our INA193A-Q1. The input bias current in the datasheet corresponds to the average value for both inputs, so the max will be 46uA for Vs=Vcm=12V
    For this device architecture, we expect the input bias current to basically be 0 for Vs=0V.
