Re: Tone generation using DAC

Are you married to this DAC (in other words, do you have to use it?)

With a DAC, you have to send it the digitized samples of the signal you
want to produce, in a continuous fashion.

If you're looking for something more like a part which can be
programmed in the manner you described, then you might want to take a
look at a DDS chip (direct digital synthesis - see Analog Devices), or
even a DSP. Depending on your application, it might be a bit overkill.

The most recent issue of QST Magazine (ARRL publication for hams) has
an article on a DDS based function generator, that might be of interest
to you...
