I am working with the OPA847 for learning op-amp theories. I am using the PSpice model available from the Texas Instrument resource. I am trying to evaluate the offset voltage. As per the theory, if I ground the inverting and non-inverting terminals (with +/-Vbias), I suppose to get amplified offset DC voltage (0 in ideal case!). Instead, I am getting a constant 4.452V DC. I have tried to nullify it but nothing works. I don't know if the problem is from a model or something. I have also attached the model I am using.
Any help would be appreciated.
Thank you.
