Abstract
Official abstract text for this publication.
A capacitive load drive circuit includes first and second capacitive loads, first and second connection path selection sections, and a voltage generation section. The first capacitive load and the second capacitive load are configured to charge and discharge in accordance with a drive signal. The first connection path selection section is configured to selectively supply a plurality of voltages to the first capacitive load, the first connection path selection section being arranged so as to correspond to the first capacitive load. The second connection path selection section is configured to selectively supply a plurality of voltages to the second capacitive load. The second connection path selection section is arranged so as to correspond to the second capacitive load. The voltage generation section is configured to generate and supply the voltages shared by the first connection path selection section and the second connection path selection section.
