- 摘要：
An ultrasonic transducer drive circuit for driving an ultrasonic transducer by outputting pulses including a positive pulse and a negative pulse to an output line is provided. The ultrasonic transducer includes a positive voltage supply circuit, a negative voltage supply circuit, a current-inflow-type ground clamp circuit configured to operate when voltage in the output line is positive voltage, and a current-outflow-type ground clamp circuit configured to operate when voltage in the output line is negative voltage, wherein the current-inflow-type ground clamp circuit is configured to enter an operation state at a time of generating the negative pulse in a state where the voltage in the output line is positive voltage, and the current-outflow-type ground clamp circuit is configured to enter an operation state at a time of generating the positive pulse in a state where the voltage in the output line is negative voltage.
