More Information
Summary:A piezoelectric drive circuit includes a first circuit which applies a voltage to the piezoelectric element and includes a plurality of transistors. A second circuit removes the residual current of the piezoelectric element and includes a plurality of transistors, and among the transistors included in the first circuit and the second circuit, transistors operated by an input signal are simultaneously turned ON/OFF by receiving the same input signal. Thus, when using a piezoelectric element as the air valve, it is possible to reduce leakage of air.
