A digital analog converter comprises an input bus, a register, a digital switch, a control unit, supplementary digital analog converter, a comparison circuit, a main digital-analog converter, an output bus. Fist information inputs of the digital switch serve as an input bus, digital switch outputs are connected to the register; output of the supplementary analog-digital converter is connected to second analog input of the comparison circuit. A unit of read-only memory (ROM), a random-access memory (RAM) unit, digital computing device, an analog commutator, first and second resistors of stepwise approximation, a module of controlled code scanning are entered in the device. |
