Part Number: F28M36P63C2
Other Parts Discussed in Thread: TMS320F280049C, TMS320F28379D, TMS320F28075, TMS320F28379S

Hi everybody,

I need to access inside DAC output directly in Concerto F28M36, but according datasheet  the output of DAC is connected to comparator, then we could not reach DAC output, is it correct? if not, please let me know how we can reach the output of DAC

    Amir,

    The 10-bit DACs are part of the comparator blocks on the device, and only act to feed the inverting input of each comparator so that an external reference is not needed.

    There is no provision on this device to bring the DAC output to a pin. 

    C2000 MCU's TMS320F28379D, TMS320F28379S, TMS320F28075, and TMS320F280049C family of devices have 12-bit buffered output DACs independent of the comparator system.

    Best,
    Matthew
