Hi Michle / Rymond
Thanks for the list. How can we get this tool to find ross reference parts? Can you include the pricing too ?

Hi Charles,
The links below will find the cross references parts.

https://bomcross.ti.com/en/home?keyMatch=CROSS%20REFERENCE&tisearch=Search-EN-everything
For instance, the latter link will find the equivalent part from our site, If you click on the last column, it will prompt for the part's technical specification, simulation models, Support & Training, and Ordering & Quality (in TI store). Click on Ordering & quality tab, it will show the part's pricing and availability information in TI store.
If you have other questions, please let us know.

Thank you Tyler
The suggestion looks great,but we need AECQ qualified alternative and this doesn't have that qualification. Please suggest automotive variant if any .

Hi Charles,
OPA388-Q1 is the automotive version of OPA388/OPA2388/OPA4388.
