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?
There is an example of a differential amplifier scematic on ADIsimPE, which is our recommended circuit simulator. All the download links you need can be accessed here:
ADIsimPE powered by SIMetrix/SIMPLIS | Design Center | Analog Devices
When you open ADIsimPE, there is a link to some Example Circuits. The one on the software uses the AD822A, but you can swap it in with the OP77 on the library.
We do have a couple of these amplifiers that have the resistors integrated for guaranteed CMRR performance. You can check this link to find out which parts might suit your application. What gain do you require and what will it be interfacing to?
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?
We just want to design a differential amplifier
As a reference OP77 datasheet page11
Can you provide these simulation example?
