Circuit device and droplet ejection apparatus

摘要

A circuit device drives actuator elements respectively associated with a plurality of nozzles to cause droplets to be ejected from the nozzles. The circuit device includes input terminals; a receiving unit; a switching unit; and a transfer unit. The receiving unit receives, via the input terminals, input signals including a terminal arrangement signal and drive signals for driving the actuator elements. The terminal arrangement signal indicates a type of assignment of signals to be assigned to the input terminals. The switching unit switches the assignment of signals in accordance with the terminal arrangement signal. The transfer unit transfers, to the actuator elements, drive signals that are input to the input terminals after the assignment of signals has been switched.
