Beefing up DAC Resolution
More accuracy on your 8-bit conversions
When you need resolution higher than 8 bits, the cost of mixed analogue/digital devices increases sharply. I wanted to show how, at no additional cost, I’ve improved the resolution of ordinary, cheap digital/analog converters, by using the output of one as a programmable voltage reference for the others.
