Abstract

PURPOSE: To obtain an operator using a high-precision micro computer with a simple constitution, by eliminating effectively the influence of conversion error caused by the characteristic on the constitution of a signal conversion circuit which perfroms A/D conversion and D/A conversion.
CONSTITUTION: Reference voltage Er, input values Ei1WEi4 of the input signal and set values Ep1WEp8 are successively selected through switches S1WS14 and are supplied to input multiplexer 4. The output of multiplexer 4 is applied to comparator CP of signal conversion circuit 5 and is compared with lamp signal Es of lamp generating circuit LG which is constituted by operation circuit OP, integrating capacitor C connected to the feedback circuit of circuit OP, resistance R1, constant- current sources I1WI3, and switches S51WS53, and the signal converted by circuit 5 is applied to output hold circuit 7 through output multiplexer 6. The output of comparator CP of circuit 5 is monitored by computer 8, and the time width obtained by controlling circuit LG is counted with clocks and is caused to correspond to the output value obtained by converting the final value of lamp signal Es.
