to a 5-bit DAC (32 steps). If the Walsh synth adds 6dB of SNR for every
doubling of Walsh functions, and if I did the math correctly, this chip
should yield a 30 dB SNR.

I could be totally wrong, since I'm just getting into this subject, but
that's my first impression. Please, someone correct me, if I'm wrong.

I wonder if several of these chips could easily be ganged together somehow,
for better quality results?


take care,
