Hi All,

Is it possible to output OPA, like the red line in the image below?

I understand that the following output route is possible.

    Hello ITO,

    Yes, that route is possible.  You just need to enable the OPAx Output PIN which is a checkbox in SysConfig.  The OPA output signal will be connected to the ADC input channel internally either way.  

    Thanks,

    Hi JD,

    Thank you for your reply.

    Next, I would like to integrate the ADC sample code with the OPA code and output from the ADC. mspm0_sdk_2_02_00_05\examples\nortos\LP_MSPM0L1306\driverlib\adc12_single_conversion

    I want the input channel of the ADC to be an internal OPA, is there a register setting I need to do?

    Best Regards,

    Ito

    Hey KZ,

    I apologize, I thought this thread was closed.  To route the signal through the OPA, you will need to add and configure the OPA in SysConfig.  There are some OPA examples that show how to do this. 

    As for connecting the ADC to the OPA output, Please refer to this table below from the MSPM0L1306 Datasheet.  Channels 12 and 13 are internally connected to the OPAx outputs.  

    Does this answer your question?

    Thanks,

    JD
