I am interested in using the ADG804 as a programmable step attenuator. However, I would be using it at frequencies as low as 5Hz. Can anyone please let me know if the device is usable to that frequency? By usable, I mean specifically, distortion at/near specification. In the datasheet the graph that starts at 20Hz appears to be just flattening at 20Hz, as if it were higher distortion below that. Could be a misprint...?
Thanks for any feedback on this!
