Re: problem in adc accuracy
2008-04-04 by jverive
Lots of factors contribute to ADC accuracy, including (but not limited to): power supply ripple, voltage reference (level, accuracy, short term stability, drift), internal electrical noise, external noise, load, temperature, and others. What specific problems are you having? Jeff

Shift 2 bits maybe? Unless you meant to throw away the 2 LSBs from the converter? Of course when averaging the readings you need to keep Mr Nyquist in mind and make sure you're sampling fast enough for the frequency domain of your signal. Sander BobGardner@aol.com wrote: > > Add
