hi,
Thank you very much, Kai, that`s very informative. I did some more tests and find this way of buttons` control as really troublesome. To obtain appropriate results I need to use a buffered R2R (like you shown) and then OpAmp before ADC input (due too high time constant of track and hold, as you said exactly). Once again, as it is said: "There is many a slip between the cup and the lip". Regards, Oleg |
