Tone generation using DAC

You can't send the data to the DAC in that format. The TLV5626 is a straightforward dual channel (Stereo) DAC not a function generator. I think it needs 8 bits of data per channel at the sample rate of the DAC. You need to write a bunch of code that takes the data in the format you mentioned and turns it into a waveform and then outputs it to the DAC. You might consider using look up tables to generate the waveforms.

Thanks... I am planning to write code and any info would be useful and helpful. I have used PWM to generate, but this is the first time using an 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...

If you have used an on chip PWM to produce a sine wave before it should be easy to change to a DAC. The sound data you send to the PWM register isn't that different to what you send to the DAC.

Thanks for for the info. I have committed to DAC. However, thanks for the info of DDS, quiet useful.

Thanks for the info. I have already written code and will do my test soon once the target board is here, will let you know, Thanks again.
