STMicroelectronics STHV748 Quad
3/5 Levels High Speed Ultrasound Pulser

STMicroelectronics' STHV748 Quad 3/5 Levels High Speed Ultrasound Pulser is a monolithic, high-voltage, high-speed pulser generator that features four independent channels. The STHV748 Quad 3/5 Levels High Speed Ultrasound Pulser is designed for medical ultrasound imaging applications, but it can also be used for driving other piezoelectric, capacitive or MEMS based transducers. STMicroelectronics' STHV748 Quad 3/5 Levels High Speed Ultrasound Pulser is comprised of a controller logic interface circuit, level translators, MOSFET gate drivers, noise blocking diodes, and high-power P-channel and N-channel MOSFETs as the output stage for each channel, clamping-to-ground circuitry, anti-leakage, anti-memory effect block, thermal sensor, and a T/R switch which guarantees an effective decoupling during the transmission phase.
