I want to use an ALD2702A 5v rail-to-rail op amp in my circuit but the circuit design software does not have it as an option. Does anyone know what I could use as a comparable op amp choice?

The ALD2702A is a 5V rail-to-rail op amp (see attached spec sheet)

Thanks for your help.

 

Since you cannot find the model of the opamp for your simulator then why not build and test the circuit instead of simulating it?

 

You can inquire from ALD if they have a model of the ALD2702 in their ALD.LIB, and if so, would they send you a copy of ALD.LIB?

See this web page:

If you want to model how the opamp might work, you should at least use a model written with the datasheet parameters in mind.

Instructions for using their models are in this document:

Thanks you for all of your help and suggestions. I am new at this but am learning something new every day. Your information is very helpful.
