Title:
液体吐出装置及び駆動回路
Document Type and Number:
Japanese Patent JP7039970
Kind Code:
B2
Abstract:
Provided a liquid ejecting apparatus including: a head that includes a piezoelectric element which is displaced by application of a drive signal; a transistor pair that includes a high-side transistor and a low-side transistor and outputs the drive signal; and a control signal generation circuit which generates a first control signal that controls switching operation of the high-side transistor and a second control signal that controls switching operation of the low-side transistor, in which the high-side transistor is set to be on and thus a voltage of the drive signal rises, and the low-side transistor is set to be on and thus the voltage of the drive signal drops, and in which the control signal generation circuit generates the first control signal and the second control signal in such a manner that the high-side transistor and the low-side transistor are alternately set to be on.
