摘要： A voltage generating circuit for a digital to analog converter divides a potential difference between a high potential supply and a low potential supply. The voltage generating circuit includes a voltage dividing circuit having three impedance elements connected in series between the high potential supply and the low potential supply. A first current source is connected to a node between the first two series connected impedance elements and a second current source is connected to a node between the second and third series connected impedance elements. The first and second current source supply first and second currents having the same value to the first and second nodes, respectively. A control circuit compares a reference voltage with a selected voltage output from the voltage dividing circuit and controls the first and second currents supplied by the first and second current source so that the selected voltage is made equal to the reference voltage.
