Abstract

PURPOSE: To achieve simple, low cost and small sized unit, by the constitution that no electronic circuit is used through the use of voltage dependent non-linear resistor.
CONSTITUTION: The D/A converter provides the zinc oxide type varistor 1 being voltage dependent non-linear resistor, a plurality of independent electrodes 2∼7 formed on the surface of the varistor 1, common electrode 7', switches 8∼13 and constant voltage power supply 14, and the electronic circuit and thin film resistor can not be used. In this D/A converter, it is equivalent that the varistors 1a∼1f sequentially different in the operation voltage (varistor voltage) are formed, and this operating voltage can arbitrarily be set by changing the electrode distance and shape. Since the constitution is taken like this, when the digital signal is replaced into ON and OFF operation of the switches 8∼13, the set current flows to the varistors 1a∼1f connected to the switches 8∼13 being ON state, and analog signal corresponding to the digital signal is shown in the ammeter A.
