For example in DACs, what exactly update rate?
But that could be the same thing as samplingMy clock indicates seconds, but I only check the time occasionally.
If the DAC has some stray capacitances that creates some settling time to achieve its final value, having a lower update ratemeans that error at the output will be lower? I say that because the output will be sampled later in the time so the output voltage may have well passed its settling timeSampling is an "input" type activity. Updating a DAC is an "output" type activity. Unlike sampling the are no real requirements imposed on updating. You can do it as fast or as slow as the application allows.
