STMicroelectronics has created a 64-channel 200V analogue switch IC for ultrasound systems, probes, piezoelectric drivers, automated test equipment, industrial automation, and process-control systems. The firm combined its own BCD6s-SOI (silicon-on-insulator) and BCD8s SOI processes to get precise bipolar analogue as well as low-voltage CMOS logic and DMOS power stages on the same chip – it can ...
