LTSpice Models Required - OPA2132 and LME49610

LME's are National parts. TI acquired National over 10 years ago. There was never a model for the device on National's website.

You might want to check the BUF634A which is a much improved buffer from TI. There is a BUF634A model, and the product has been discussed on DIYAUDIO.

There is a OPA2132 model for TINA, probably encrypted. A TINA version is freely available from TI.
