Abstract
PURPOSE: To obtain a digital-analog converter featuring a number of merits and effects by securing a vertical connection for several resistance elements having the switch elements connected in parallel and then supplying a constant amount of current to these resistance elements to turn on and off each switch.
CONSTITUTION: Resistance elements R1∼R4 having switch elements S1∼S4 connected in parallel are connected vertically to form a circuit. A constant amount of current is then supplied I to the circuit to turn on and off switch elements S1∼ S4 according to each bit information of the input digital data, thus the short control being given to the resistance elements. The resistance value of each element of R1∼ R4 is set previously to the weight corresponding to each bit of the input digital data. Thus, the analog voltage value equivalent to the input digital is obtained based on the voltage drop of the circuit.
