[sdiy] Which programable chip?

[Jason Proctor]

i slaved up a TLV5618 SPI DAC chip for 2 channels of analogue output. 
that too was easier than i thought it would be. the 5614 chip gives 4 
channels from the same sw/hw interface.

there are 3 (IIRC) PWM output pins too, but i didn't find a good way 
of converting PWM to clean DC.
