Abstract
N drivers convert n digital values into n voltages. N amplifiers amplify the n voltages, thereby generate n drive voltages. An amplifier voltage supply supplies an amplifier voltage for driving the n amplifiers. An amplifier voltage controller detects a maximum digital value among a plurality of digital values, and sets the amplifier voltage to a voltage value dependent on the maximum digital value.
