GBW of OPAMP - wider design limits - STM32C5

[mechatron]

Hi,

Any reason why the GBW of the OPAMP is having such a wide tolerance? Is it purely because the values are best-worst case design calculations?

In comparison, the Gx and Fx variants has better limits.

Dear  ​@mechatron 

Thank you a lot for pointing to this GBW wide tolerance representation in our documentation, after full analysis with our validation and design teams, we confirm an issue on that line and should be:

• Min : 6MHz   
• Typical : 15MHz

20MHz value is only for No load and should not be there. We are tracking this Change and update with internal reference CDM0063403.   Thank you again and much appreciated.

Regards,

STOne-32
