Hi SIr/Madam, 


I was planning to use ADUM4190/ADUM3190 in isolating Analog Audio input signals. And few queries with respect to usage. Could anyone please help my concerns solved. 


  1. Can I use ADUM4190/3190 for Audio application. 
  2. If It can be used in Audio application, What would be the required matching circuit required. 
  3. How to get un-amplified signal (Unity Gain)
  4. I would be interfacing the output Analog signal with Codec IC. What should be the matching circuit required for interfacing  with WM9081 codec.
