Abstract
PURPOSE: To obtain an economical multi-channel device featuring a high speed and accuracy by securing the accurate analog output by correcting the output error of the simple D/A converter of each channel with the holding value of the analog holding circuit.
CONSTITUTION: Analog holding circuit 5 is provided to each of channels 11∼13, along with simple D/A converter 4 to analogize the digits of the input signals to be converted through chaannels 11∼13. Furthermore, one unit of standard D/A converter 3 is provided to give analogization to all digits of the input signal, and at the same time the sum of the output of circuit 5 of each of channels 11∼13 and the output of converter 4 with the output of converter 3 periodically in terms of channels 11∼13. And the holding value of circuit 5 is corrected periodically in order to secure a coincidence for the comparison result. Thus, the accurate analog output can be delivered from channels 11∼13, obtaining an economical multi-channel converting device featuring a high speed and accuracy.
