Abstract
The potentiometer includes a ground terminal 1, a power terminal 2, a resistive element 4 provided between the ground terminal 1 and the power terminal 2, a sliding portion 18 for sliding on the resistive element 4, an output terminal 3 for obtaining the output in response to the position of the sliding portion 18, a reference voltage terminal 5 provided on a reference position RP where a reference voltage Vref should be generated, and a power supply 6 for applying the reference voltage Vref to the reference voltage terminal 5. The reference voltage terminal 5 is provided on the reference position RP where the reference voltage Vref should be generated. The reference voltage Vref is sustained at the reference position RP, because the power supply 6 applies the reference voltage Vref from the reference voltage terminal 5 to the resistive element 4. The offset can be adjusted rapidly due to the regulated voltage at the reference position RP in spite of a productive variation of the resistive element 4. The control system can be stabilized due to the regulated voltage at the reference position RP.
