I am using the ADA4899-1YCPZ.
The data sheet states offset voltage: 230uV Maximum.
When I used it, I had an offset voltage of 1.3V.
I put the result of the simulation as an attached file, and I used the PCB circuit diagram I actually created as a buffer like an attachment file.
Tell me why I do not understand why an offset voltage of 1.3 volts occurs.
