FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, in particular to analogue-to-digital converters and can be used in digital systems for measurement of analogue values. ADC using transient process in RC circuit comprises (fig) microcontroller 1, reference voltage source (RVS) 2, resistor 3, capacitor 4. Resistor 3 and capacitor 4 are connected to first input of analogue comparator (AC) built into microcontroller 1 by first outputs (in fig. AC is not shown), output of RVS is connected to the second output of resistor 3, the second output of capacitor 4 is connected to common power bus, the second output of AC of microcontroller 1 is connected to the first output of analogue signal source, the second output of which is connected to common power bus.
EFFECT: increased accuracy.
