Abstract: An ultrasonic probe includes: an ultrasonic transducer; an amplification stage; a bias circuit, which determines a bias voltage on an input terminal of the amplification stage; and a selector having an intermediate node, a high-voltage switch between the intermediate node and the transducer, and a first low-voltage switch between the intermediate node and the input terminal. A control unit controls the high-voltage switch and the first low-voltage switch so as to alternately couple and decouple the amplification stage and the transducer. A precharge circuit determines a precharge voltage on the intermediate node as a function of the bias voltage, before the amplification stage and the transducer are coupled.
