Geneva—Built using its advanced high-voltage BCD mixed-signal technology, STMicroelectronics' latest low-noise ultrasound pulse controller provides four independent channels, each of which generates precisely controlled high-voltage pulses to drive piezoelectric crystals or other transducers.
Dubbed STHV748, the 5-level pulser enables the next generation of high-performance ultrasound imaging systems in a small form factor. The STHV748 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 include ±90V dual independent high-voltage supplies; ±2A source and sink current in pulse mode and continuous wave mode (CW); and a dedicated CW mode pulser for low power and ultra low jitter (down to 20ps).
The STHV748 is housed in a lead-free QFN64 9.0 x 9.0 x 1.0mm package.
Pricing: $11.95 in quantities of 10,000.
