dacs

Most USB DACs work just fine when running on computer power, without any hitches, glitches, or strange noises.

Surprisingly or not, PWM circuits (a counter and binary comparator) are more common than DACs on today's microcontrollers.

Since DACs (or ADCs for audio input) have analog sections, you have to deliver power that meets those specifications.

Yes, you can screw up DAC design and execution, but nowadays most DACs are very good.

It's a very draining task that I restrict to comparing amplifiers/DACs and speaker setups, and I'll always use Flac for that anyways.

You Bitcoin people keep going on about DACs.

Another interesting thing you could do with the VGA was use slight color deviations to get 256 shades of gray instead of 64 (the VGA had 6-bit DACs).

Headphones and DACs can make a real difference.

If you haven't heard of Schiit, it's a fascinating story of a small company that builds high end and low end headphone amps/dacs, for much less money than competitors.

> a pair of very fast dacs hooked up to the 16 address lines of my computer and another dac hooked up to the databus.

We only had one day to prep for demo day and asking the Z80 kids to do DACs, and a vector algo, and trig all in one day might have been asking too much.

I used to have something like this: a pair of very fast dacs hooked up to the 16 address lines of my computer and another dac hooked up to the databus.

I would imagine whatever took a "sheet of paper" sized development board with dedicated hardware DACs and eproms around 1990 could be done as a single chip solution today, assuming you can find a single chip solution that actually has two on board DACs.
