    Hello Shengnan,

    We normally don't have this as a specification as it does change for each gain.  The number below are typical and not guaranteed and can vary from device to device.  The final datasheet should have a typical curve of IB vs Vsense.  

    INA296A1: 50kΩ

    INA296A2: 25kΩ

    INA296A3: 10kΩ

    INA296A4: 10kΩ

    INA296A5: 5kΩ
