The scheme is fully removed from dataset to the ADC icl7107. When used in BP, and the like - does not need to measure a negative voltage, therefore, it is possible to collect on 7107 voltmeter with a single polar power supply. Chip happy demanding to nutrition. If not configured for the reference and the reading jump - put at the entrance of the electrolyte is of the order of 1000 UF + 0.1 UF ceramics.
