Hi team

INA282-Q1 D/S say Input bias current = TYP 25uA per pin.

so total input bias current would be TYP 50uA(= 25uA 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 INA282-Q1. The input bias current in the datasheet corresponds to the average value for both inputs, so the max will be 50uA for Vs=5, Vcm=12V.
For this device architecture, we expect the input bias current to basically be 0 for Vs=0V.
