I would dearly love to have a SPICE model for the TI OPA2604

Hi, Jim,

That is a TINA model which is our comparable tool to LT Spice.

You can download TINA off our website for free.

I don't think we have a generic spice model; let me move your post to our Webench forum for further discussion.

Jim,

Actually, you want to pull the PSpice model that is in the product folder. Unzip the file and use the OPA2604.lib file. It can be imported into LTSpice by following the directions from the LTSpice users forum. LTSpice will automatically create a symbol for it as well, but you will want to keep track of the pins:

NON-INVERTING INPUT - Pin 1
INVERTING INPUT - Pin 2
POSITIVE POWER SUPPLY - Pin 3
NEGATIVE POWER SUPPLY - Pin 4
OUTPUT - Pin 5

This is documented in the .lib file header as well.

This .lib file is unencrypted and can be used directly from the .zip file.

Thank you, Britt!   But after having spent some time looking for "the product folder" I have to say all I see are data sheets and HTML pages. Where can I find the OPA2604 data folder that contains the file "OPA2604.LIB"?  By the way the datasheets are making me want to use this chip so this is getting more important by the minute. - Jim Tonne
