Abstract

PURPOSE: To reduce the conversion time and to make easy for circuit integration, by detecting the coincidence of the digital input value and the output value of the counter at the coincidence circuit and holding the output voltage of the saw tooth wave generating circuit at that time point with the sample hold circuit.
CONSTITUTION: The clock output a of the clock generation circuit 1 stable using crystals is counted at the counter 2. The saw tooth wave generating circuit 3 is driven in synchronizing with the counter 2. The digital input to be converted is tentatively stored to the register 4. The digital input value stored in the register 3 and the output value of the counter 2 are inputted to the coincidence circuit 5, and when the both are in agreement, the coincidence detection output d is outputted to the sample hold circuit 6. The circuit 6 samples and holds the output voltage V0 of the circuit at that time point. Further, the analog voltage corresponding to the digital input value can be obtained.
