ADuM3190 as an isolator

Hello,

 

We have a device that transmits analog signals between 0 to 3.3Vs (1.65Vdc, +/- 1.65Vpp) to the ADC pins of our MCU. We want to isolate these two parts with an analog isolator that has unity gain (~1), can take 3.3Vs as supply and can reproduce the signal with a few microseconds delay (ADC pins read the signal every 25 microseconds). Can we use ADuM3190 for this purpose and do you know any example schematic?

 

Thanks
