Abstract

PURPOSE:To decrease number of components, by connecting a weighted resistor to a parallel output terminal of a shift register to which a series digital signal is inputted, commonly connecting other ends and connecting the point to another resistor. CONSTITUTION:A digital input is inputted to a shift register 7 to be parallel outputs D1-D3. Weighted resistors R8-R10 are respectively connected to the outputs D1-D3 and other ends of the resistors R8-R10 are commonly connected. The common connecting point is taken as an output terminal Vout and grounded via a resistor R11. The resistance values are as R9=2R8 and R10=4R8 and an analog voltage in response to outputs D1-D3 can be obtained at the terminal Vout.
