MSPM0 OpAmp interconnection schematic

Jan Cumps

Several MSPM0 controllers have more than one OpAmp on board. There are MUX settings to interconnect them.

I couldn't find a generic picture of how two OpAmps can be wired up, so I made one. It's based on Figure 17-8. Two OPAs in Difference Amplifier Configuration of Texas Instruments Technical Reference Manual for the MSPM0 L-Series 32-MHz Microcontrollers.

Some connections aren't drawn, but have a label name. Comment if you 'd like to see some of them as a line.

  • Nice, those two op-amps look very flexible.

    It's great how the initial config is just a matter of using a graphical tool (can be local or browser-based). Screenshot below in case anyone's not seen what that looks like.

    Personally I really like how the generated code is specific to certain files that never need touching, whereas other microcontroller development environments generate code interspersed into the main code.
