Could someone tell me what the characteristics of the amplifier inside this part please, I would like to know so I can do some stability analysis. Many thanks Andy C.

Hello Andrew,
We have pspice models for this part. They are listed in the tools tab of the commercial part's product page on ti.com at the link below. These models are applicable to the EP versions of the part.

Let me know if you have any other questions, or otherwise, please mark this thread as resolved.

Hi Kirby, sorry I don't need a spice model I need the amplifier parameters that's inside the part. I need the open loop gain / bode plots and the output impedance of the amplifier. What I need is to be able to calculate the phase margin of this part with the various capacitive loads. Can you help in getting this information for me. Many thanks Andy C.

Hi Andy,
It is unlikely TI will be able to provide this information, but I am investigating. Most of TI is not working this week so I won't have a definitive answer until next week.

Hi if this information is difficult to obtain the could TI give me some information on how a stability analysis for this part can be done. Can this be done in pspice, if so are there any notes on how to do this. Regards Andy

The product was fully characterized over temperature under the conditions shown in the datasheet. I am investigating if there data available to share.

It doesn't look good for getting additional information, but I am still tracking down some resources. Not everyone is back from the holidays yet.
