ABSTRACT:
A liquid ejection apparatus includes an element that is charged and discharged so as to perform an operation to eject a liquid, an analog signal generating unit that generates an analog signal having a voltage change pattern for determining the operation of the element, a charging transistor that amplifies a current of the analog signal while the element is charged, and pushes the amplified current toward the element, the charging transistor having a current source terminal, to which a current source is connected, and a push terminal for pushing the current, and a current source connector that selects at least one current source from among a plurality of current sources according to a voltage of the analog signal, and connects the selected current source to the current source terminal.
