Ultrasound controller is highly integrated

Built using high-voltage BCD mixed-signal technology, the STHV748 ultrasound pulse controller provides four independent channels, each of which generates precisely controlled high-voltage pulses to drive piezoelectric crystals or other transducers. The controller integrates CMOS digital control logic, analog level translators, MOSFET gate drivers, and high-power n- and p-channel MOSFET output stages in a fully self-biasing architecture.

Key features of the device include ±90-V dual independent high-voltage supplies; ±2-A source and sink current in pulse mode and continuous-wave mode; and a dedicated CW mode pulser for low power and ultralow jitter. The part also offers up to 20-MHz frequency. a 2.4 to 3.6-V CMOS logic interface, and jitter down to 20 ps. ($11.95 ea/10,000 — available now.)
