DIGITAL-TO-ANALOGUE CONVERTER Russian patent published in 2012 - IPC H03M1/66 

FIELD: physics.

SUBSTANCE: digital-to-analogue converter (DAC) has a direct current generating unit whose inputs are inputs of the DAC, a photodetector, a signal amplifier whose output is the output of the DAC, a set of light-emitting diodes whose number is equal to the capacity of the DAC, and lying at a distance from the photodetector depending on the weight of their digital binary bit, and a mirror lying in parallel to the plane of the photodetector and the set of light-emitting diodes.

EFFECT: faster operation and high accuracy of conversion of the digital-to-analogue converter.
