Hi Jonathan,
Thank you for the answer!
The analog inputs that are connected to our system are not determined and they could act like in single ended mode of operation, where the negative input is connected to ground and the positive swings.
Our circuitry should be able to switch between differential to single ended.
I guess that we will not be able to use the AD7609 device for our purposes... am I right?
Can you recommend on another device that could do the work?
We are looking for a device/circuitry that will replace an old design.
If you want, I can send you the old design by mail.
Thanks!
Avi
