Making a DAC from an Op Amp
- burntrelish1273 10y agoNeat. Basically, a summing amplifier hooked up to an inverting amplifier where each summing input resistor value is double the next. For real use, each digital input could also use some sort of signal level filtering, probably some sort of logic buffer which can drive all these pins and reduce load on the input. (In idealized simulation, it's fine as is.) https://en.wikipedia.org/wiki/Operational_amplifier_applications#Summing_amplifier https://en.wikipedia.org/wiki/Operational_amplifier_applicat... https://en.wikipedia.org/wiki/Operational_amplifier_applications#Inverting_amplifier https://en.wikipedia.org/wiki/Operational_amplifier_applicat...
- marclave 10y agoTotally! Thanks for the links, checking these out! Haha yeah totally sim life !== implementation
