I am using the Channel D of ADA4522-4 as a voltage buffer.
For testing, I short the inverting input of channel D to the output of channel D. I apply -10V to the non-inverting input of channel D.
My positive supply voltage is at 13.5V and negative supply voltage is at -13.5V.
I expect the output of channel D to be -10V. However, when I measure it with multimeter, the output is at 13.5V as shown below:
What do you think my mistake could be? When I simulated this simple circuit with LTSpice, the output was as expected.
Do you have any suggestions?
Thank you very much for your help!
