The imput impedance of AD7124-8

Hi,

Could anyone tell me what the imput impedance of AD7124-8 would be?

I could not find any infomation about it on its data sheets.

Thanks!

    Hi,

    We list the input current specification rather than specify the input impedance. The input impedance can be calculated from this input current specification. When buffer is enabled, the absolute input current is +/-1nA for low power mode, +/-1.2nA for mid power mode and +/-3.3nA for full power mode. With Gain > 1, the input buffers are automatically enabled. Thus, it can handle any significant source impedances which allows external filtering necessary in your application. When, un-buffered the absolute input current is +/-2.65uA/V. These values can be found in datasheet specification section.  

    Thanks,
