We have received a request to the Precision Amplifiers e2e forum asking that the OPA551FA (DDPAK) package added to the PCB thermal calculator. I wasn't familiar with this online tool until we received questions about it. I have reviewed the Applications Report associated with the calculator, but that doesn't answer their question about adding a model. When I check the calculator it shows that it supports only one of our PRAMPS power op amps, the OPA564.
The Applications Report originated in 2010 and was updated in 2019. Is the thermal calculator considered active, where additional products can be added or is considered obsolete? If it is active the customer is requesting the OPA551FA be added.
By the way, the Part Number entry point in the "Create a new thread" did not list the OPA551, and wouldn't allow me to enter it. Therefore, I was forced to select the "I don't have a part number" option, which of course isn't true.
Thank you, Thomas
