4 Design Considerations

When generating an output waveform, here are a few things to consider:

  1. Waveform period is equal to the DMA update timer period times the number of points in the waveform. More points enable a smoother waveform but a longer period.
    1. At maximum speed, consider the DAC8 settling time of about 1.5μs
  2. In this example, there are 256-points and the DMA updates the points every 40μs.
    1. 256 point × 40μs = 10.24ms waveform period = approximately 98Hz output
  3. Some MSPM0Gxx devices have standalone 12-bit DAC modules that do not have to be buffered by the integrated OPAx.
