Zusammenfassung:A ladder resistor circuit includes a ladder resistor including first to k-th resistors connected in series and outputting a plurality of voltages by receiving a first potential and a second potential, a first correction resistor that has a resistance value equal to a series total resistance value of a resistor group constituted of first to r-th resistors among the first to k-th resistors, a second correction resistor that has a resistance value equal to a series total resistance value of a resistor group constituted of (r+1)-th to k-th resistors, and an amplifier that receives a potential of a connection point between the first and second correction resistors at an input terminal thereof, and has an output terminal thereof connected to a connection point between the r-th and (r+1)-th resistors.
