ADA4857 pspice Model

I am trying to use the ADA4857 to generate a circuit model of a state variable filter in order to compare with measured results.  In our implementation, we are using a single supply (+5V/0) on the ADA4857.  When using the pspice model of the ADA4857 in Microwave Office, the pspice model does not work with a negative supply the is greater than -0.9V.  Is there something in the pspice model that I can change that will allow the pspice model to work with the negative supply grounded?

    Hi John,

    You can download the NI Multisim simulation software forfree from the website.

    This will help with your ADI part simulations.

    That is the first time I hear of the ADA4857 model not working on signle supply.

    I'm wondering if it is caused by your simulator.
