I intend to access memory from the DAC when using it as a wavetable oscillator. I have bought a large number of Winbond W25Q128 128Mbit SPI flash memory chips, however, they are 3.3v max.
That's not really a problem though - the PIC16F18346 and the DAC8830 runs fine on 3.3v, I just need to remember that when adding memory! I've tested and it looks ok. I can however NOT use 5v for the DAC reference, so to get the same output amplitude we need to recalculate the charge voltages.
