INA597: Input bias current

Shaury Anand
Intellectual 1740 points
Part Number: INA597

Hello,

What is input bias current of the amplifier? The common mode input impedance of INA597 is 9kohm (given in the datasheet). The input bias current of the amplifier should be 4mA at 36V common mode input voltage. However, figure-13 in the datasheet specifies that input bias current will be <3nA. 

Regards,

Shaury
