Analog-Digital-Umsetzer

Abstract

An analog / digital converter includes amplifiers, an analog switch connected by its inputs to the amplifiers and a unit of comparison has multiple floors receiving its entry the output signal from the switch. The converter further includes a translation device has seriel code translates the code in parallel from the unit in a submitted pulse sequence at the entrance of a digital switch. The converter is provided with a reversible counter and a counter the inputs of the two counters being connected to the switch; The output signal from the counters is sent to a unit code has reminders-evacuations and a code analysis unit is connected via a register has a unit determination of the scan mode, the output signal from the unit being transmitted to the unit and an analog / digital converter connected by its output at the entrance the first amplifier. A control unit predetermine a working algorithm for this converter, so that the direct conversion mode, the conversion method of the analog input value in a pan-bit code occurs after K cycles, while in the metrological control mode, binary numbers are determined, the metrological characteristics of deviation exceed acceptable values.
