An ultrasonic transducer probe comprises an array transducer and a microbeamformer ASIC (46a, 46b) containing transmit amplifiers and receive circuitry for operation of the array transducer. For higher power operation, the drive current of the amplifiers is increased, rather than the transmit voltage. The elements of the array present a low impedance to the transmit amplifiers for increased drive current by their construction of thin layers (12) of piezoelectric material which are electrically coupled in parallel to an amplifier while being mechanically coupled in series for ultrasound transmission.
