PSpice model for OP270Z

Hi ArvindSwarup,

FYI: OP270 is labelled as not recommended for new designs.

There is a pspice model for this part already: https://www.analog.com/en/products/op270.html#product-tools

I've imported the model into LTspice which you can download for free:

Thank you for your prompt response.  Is there a recommended OP amp I can utilize.  This is for a satellite application and am looking for a Rad tolerant device (TiD 30K Rad).  OP270Z appears in the DCSS list suitable for Space (flight PN5962R9468002VHA).   

Any equivalent device would you recommend. Bread board evaluation used ADA4896-2 (commercial device not recommended for space use) and would appreciate your suggestion for an equivalent replacement with a space approved packaged device.

Best Regards

Hi Arvind,

I have limited visibility into Space / flight products. So unfortunately I cannot help you but hopefully other people on this forum can. Sorry.

The following are space qualified, but I don't know what the rad tolerance is:

AD8671S, ADA4077-2S, ADA4084-2S, and AD8629S.  See:

My choice for your application would be the 4077.
