[Тимофеев Михаил]

The ADS1282 offers outstanding specification, but not very useful in the wide-scale DVM application range due to low input and reference voltages.
Within a year I'm trying to develop a design of the selfcal 7.5-digits DMM with ADS1282 ADC. Reference (+/- 10V) is a aged 1N829A with 0.03ppm noise and 2nd order TC correction, downscaled to +/-2.5 V with zero TC divider.
