Dear Russell,
Thanks for your reply, Many of your errors can be solved by calibration I have seen a lot of people [ including myself ] use Cerment multiturn pots for caliberation purpose. My main worry is how can one rely on a caliberation stuff having 100PPM/C drift. In most of the designs we assume approx 40 C variations in the temperature. This 40 C will cause approx. 100*40 = 4000PPM error that is 0.4% and this 0.4% is enough to disturb even 8bit design what about 10bit or 12bit things. Is this really a reliable means of caliberation. Thanks & Regards, Prahlad Purohit |
