Abstract

An analog-to-digital converter comprises amplifiers (2), an analog switch (3) connected with its inputs to the amplifiers (2) and a multistage comparison unit (4) receiving at its input the output signal from the switch (3). The converter further comprises a serial code translator (5) ensuring the translation of the parallel code coming from the unit (4) into a sequence of pulses sent to the input of a digital switch (6). The converter is provided with a reversible counter (7) and a counter (8), the inputs of both counters being connected to the commutator (6). The output signal from the counter (8) is sent to a code rollout-rollin unit (10) and to a code analyzing unit (9) which is connected through a register (13) to a scanning mode determining unit (12), the output signal from the unit (10) coming to the unit (12) and to an analog-to-digital converter (11) connected with its output to the input of the first amplifier (2<u1>u). A control unit (18) presets a working algorithm of the said converter, so that in the course of direct conversion mode the process of conversion of the input analog value into a n-bits p-code takes place after K cycles, whereas in the course of metrological control mode bit numbers are determined, the deviation of metrological characteristics of which exceed admitted values.
