AD8676 output impedance

Hi,

 

I am going to use an AD8676 as a follower due to its very low noise voltage density as low offset voltage.

 

The AD8676 is loaded by a AD4932 to convert the previous voltage from single to differential ended signal in order to drive AD7960 ADC.

 

So I need to know input and output impedance, information I was not able to locate in the datasheet.

 

I was able to find a post about the AD8676 input impedance:

So the input impedance is about 1Gohms... perfect.

 

But what about the ouput impedance?

 

 

Thanks for your help,

 

 

Luc
