STMicroelectronics announced the STHV748, which is a highly integrated low-noise ultrasound pulse controller. The STHV748 includes four independent channels, each of which generates precisely controlled high-voltage pulses to drive piezoelectric crystals or other transducers. The device is housed in a lead-free QFN64 9.0 x 9.0 x 1.0mm package. The STHV748 is available now at $11.95 in quantities of 10,000. The device is ideal for ultrasound imaging systems in a small form factor.
