The invention relates to the field of electronic and measuring equipment and can be used as a reference divider attenuator for electric and electronic circuits, and in set of digital-analog and analog-digital converters. The method of construction of an divider attenuator is in provision of a line of N connected in series resistors with same nominal values, where the lowermost end output of the line of resistors is connected to common output of divider attenuator, and all the outputs of the line, except of the lowermost end one, through keys code-controlled by the first decoder are connected to the output of the device. The device input, are connected to the end upper terminal and next terminals of the line downwards through at least N/2 keys code-controlled by the second decoder. The technical result of the invention is in increase of resolution capability of the divider. |
