First, I'd try putting out DC voltages. 5V, 0V, and something in-between.
As you may know, a digitized sinewave needs a known frequency and sample rate.
And since the TDA1543 operates from a single +5V power supply it can't put-out the negative half of a sine wave so the digital data has to be biased/offset. (Most DACs & ADCs work that way.)
Thanks for the explanation, I thought it could be done like other dacs for arduino. I was not looking to generate a wave, it was to play audio through a speaker
