摘要：In the analog current output circuit according to the present invention, a risingstart position and a tilt of an internal control voltage are set such that it crosses, at themaximum of an analog output current, a load end voltage obtained when the resistance

of a load is the one near the center of a specification range. According to a comparisonresult in a comparator, a switch causes a DC/DC converter to input a high referencevoltage and causes an output transistor to output a high power supply voltage when theinternal control voltage is smaller than the load end voltage and causes the DC/DCconverter to input a low reference voltage and causes the output transistor to output alow power supply voltage when the internal control voltage is larger than the load endvoltage.
