Supertex's New High Voltage, Analog Switch Occupies Less Board Space Than Electromechanical Relays in Medical Ultrasound Prob...

Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog
and mixed signal integrated circuits (ICs), today introduced the
HV2809, a thirty-two channel, high voltage, analog switch IC
designed for use in medical ultrasound imaging systems as a probe
selection device. It replaces the typical electromechanical relays
performing the probe selection function and takes up less printed
circuit board (PCB) area, emits no audible noise and increases
system reliability.
The HV2809 serves as a sixteen-pole, double throw (16PDT), high
voltage switch array. Using Supertex's proprietary HVCMOS
technology, the IC efficiently controls analog signals with low
power CMOS logic and high voltage bilateral DMOS switches. It
features a very low quiescent current of 10µA for low power
dissipation and a bandwidth frequency of up to 50MHz. The HV2809
also has an enable logic control, which allows it to be configured
for 2:1 or 4:1 ultrasound probe select.
"Using the HV2809 to control medical ultrasound probes offers a
number of advantages over electromechanical relays," states Jimes
Lei, Director of Application Engineering for Supertex. "As
technology moves forward and medical ultrasound systems become more
compact, replacing the mechanical relays with the HV2809s will
reduce board area, component height, and system weight."
The HV2809 is available in an 8x8x1mm 56-lead QFN package
(HV2809K6-G). The part is RoHS compliant. Samples are available
from stock. Lead-time for production quantities is 4-6 weeks ARO.
Pricing is US$14.51 each for the HV2809K6-G in 1K quantities.
