Hi ALL,
I designed a circuit on TINA by giving a 12 volt AC and ensured both grounds(I/P and O/P of ISO224) are isolated.
I grounded the -ve terminal of the differential output of ISO224 and gave the output to a voltage follower.
The sine voltage of 12 volt amplitude is without a DC bias.
I found the voltage at the output of ISO224 is having some DC bias which is unexpected to me. The simulation and the results are attached.
Please comment.
