Hi Sir

Could you please provide OP77 spice model pin define?

These model have 5 pin

But I not sure the pin define

And could you please provide some simulation example about these model?

Thanks

  • Hello Daniel, 

    Are you using the SPICE model from the OP77 webpage? If so, the node assignments are below:

    1 - non-inverting input

    2 - inverting input

    99 - positive supply

    50 - negative supply

    39 - output

    What simulation examples do you require? Circuits for testing parameters? If you could specify what you need, I would be glad to provide some examples.

    Also, please note that the OP77 has a newer generation device, the ADA4077. It has higher bandwidth, lower noise, and low bias current.

    By the way, what is your application?

    Thanks!
