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.
