Abstract

PURPOSE:To make it possible to simplify the constitution and also to give effect to D/A conversion of even a digital value of a large number of bits in a short time by dividing the digital value into several and by making the final output value of an integrating circuit correspond to the digital value. CONSTITUTION:Digital value Di of 16 bits is divided into three regions K1, K2 and K3. The converter consists of constant current circuit 1, integrating circuit 2, output holding circuit 3, logic circuit 4, etc., and in circuit 4, control circuit TC composed of a microcomputer, etc., divides Di stored in register RE into regions K1-K3, counts sequentially data n1-n3 of respective regions by clocks to output time-width signals N1-N3, thereby controlling swtiches S1-S3 of circuit 1 while controlling switches S4 and S5 by generating reset signal RS and sampling signal SS.
