The variable resistors Rik to Rin up to the variable resistor (eg, the nth variable resistor Rik) adjacent to the n EM driver may be greater than the reference resistor value Rref. When the resistance values of the variable resistors Rik to Rin are greater than the reference resistance value Rref, the comparator 934 sequentially converts the first EM output signal Vout1 to the k-1 th EM output signal Voutk-1. However, the kth EM output signal Voutk to the nth EM output signal Voutn may not be output. For example, the comparator 934 operates from the period in which the EM driver 932 outputs the first EM signal EM1 to the period T1 in which the EM driver 932 outputs the k-1th EM signal EMk-1. An EM output signal Vout may be output. The comparator 934 operates the EM output signal ( Vout) may not be output.
