Abstract

PURPOSE: To obtain optional output resistance and control voltage characteristics, by changing and connecting the fixed resistor group which is mounted outside in accordance with the control voltage.
CONSTITUTION: As for the control voltage Vc which has been input to the Vin terminal, the voltage level is compared by the comparators of (n) pieces CMP1W CMPn in the comparator circuit 1, and a signal corresponding to the value of the control voltage concerned is provided to the Zener diode circuit 2. The Zener diode circuit 2 converts the input signal to the logical signal level, and generates the switching signal groups S1WSn. The switching signal groups S1WSn drive the switching circuit 3, change the fixed resistor groups R1WRn which are mounted outside according to the user's specifications, in accordance with the value of the control voltage Vc, and output the necessary resistance value to the Rout terminal.
