ST’s first product in the family of ultrasound transmitters, the STHV748, is a high-voltage, high-speed pulse generator featuring four independent channels, designed for medical ultrasound imaging applications. The device can also be used for driving other piezoelectric, capacitive or MEMS based transducers. It features embedded low-power, floating high voltage drivers, and a dedicated half bridge which is available in order to reduce power dissipation during continuous wave mode down to 0.1W.
