Abstract

PURPOSE:To use only a digital-to-analog (D/A) converter, by storing plural digital data temporarily on an RAM, reading out in order and inputting them to D/A converter and storing the output of D/A converter in a holding capacitor. CONSTITUTION:Plural number of digital data are inputted to an RAM3 through a data bus 2 and are changed into writing operation through a changeover circuit 5 by a switching address bus 4 to store in the RAM3. The circuit 5 reads the data stored in the RAM3 by using a counter circuit 7 which is operated by an oscillator 6 in order and inputs them in the D/A converter 8. Then, the circuit converts the digital data into analog data and simultaneously when supplies them to the input of an analog multiplexer 10 by passing through a buffer amplifier 9, it selects the address of the analog multiplexer 10 which corresponds to the address of the RAM3. Then, analog data are converted and outputted in order and are stored in the holding capacitors 12-1-12-n. consequently, they are outputted from buffer amplifiers 13-1-13-n.
