Summary:PURPOSE:To improve the reliability of the operation of a multiplexed analog outputting circuit by installing a high-level selector circuit composed of diodes to the buffer circuit of the multiplexing series. CONSTITUTION:Doubling is performed by analog outputting circuits 10A and 10B of A and B systems. A parallel circuit of a short-circuit protecting resistance 12 and speed-up capacitor 13 is installed to the output side of a buffer amplifier 11 to which analog outputs are supplied. A diode 15 is connected between the parallel circuit and output terminal ta (tb) and, at the same time, a noise preventing capacitor 14 is connected between the cathode of the diode 15 and earth. A high-level selector circuit composed of the diodes 15 are formed by connecting the terminals (ta) and (tb) with each other. Therefore, the higher side of the output level of the buffer amplifier 11 is selected. Therefore, reliability of the operation of a multiplexed analog outputting circuit can be improved.
