Abstract

PURPOSE:To simplify the constitution of the entire system and to reduce consumed current, by operating a current switch 3 and a current source as a plurality of D/A converters in time division operation in common, through the operation of an output/input selecting changeover switch. CONSTITUTION:A plurality of lattice type resistance circuit networks I1, I2, are prepared, and a current switch 3 inserted between a current source 4 and the lattice type resistance networks I1, I2 is prepared by the number of bits of digital input signal, and the system can be operated as a plurality of D/A converters in time division operation, in the form that the current source 4 and the current switch 3 are used in common by the operation of output/input selecting changeover switches 7, 8.
