PSPICE help

Dear ALL,

I want to simulating a op-amp circuit in PSPICE. However, I can't found the pspice model of this OPAMP in PSPICE library. How can I can build the pspice library of this opamp by its datasheet? Please advise.

Regards,
Keith

Hi,

Why don't you give the part number of the opamp you want to simulate ?

There is a lot of free available models on opamp provider's site. If you cannot find it on those sites, maybe someone has it and can give it to for free. Just give the part number and someone will help you.

Did u try the model editor in pspice?That can be a very good starting point to start modelling.

Re: PSPICE help

if u can enter ur design as a schematic u can choose an opamp & there is a button that generates spice netlist/model in a text file
just copy-paste the output model
