Abstract

PURPOSE: To carry A/D conversion and D/A conversion into effect through nearly the same hardware by using a lamp signal generating circuit, whose lamp signal is variable in slanting angle, for an operator which provides compound arithmetic by receiving and sending analog signals, and then by bringing its switching under the control of a micro-computer.
CONSTITUTION: Through input multiplexer 3, reference voltage Er, and input signals Ei1WEi4 are selected in sequence. Input signal Ei and currents i1Wi3 supplied from constant current sources IS1WIS3 with switches S41WS43 closed are applied to operational amplifier OP and then compared by comparator 42 with lamp signal Es to obtain digital signals, which are sent in sequence from lamp signal generating circuit 4 to microcomputer 7. Digital values stored in micro-computer 7 are converted into analog vaoues as lamp signal Eso when switches S41WS43 are turned ON, and they are outputted by output holding circuit 6 via output multiplexer 5.
