Beamforming Source Driver From Supertex Incorporates Eight-Bit Pulse Amplitude Modulation
Programmable MD2134 Has Fifteen Independent Output Level Registers
(firmenpresse) - SUNNYVALE, CA -- (Marketwire) -- 09/15/11 -- Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced the MD2134, a high speed source driver to be used in a pulsed current waveform generator for medical ultrasound imaging machines. The IC can also be used in non-destructive image evaluation, metal flaw detection, and sonar phase array applications.
MD2134's output stage is designed to be the source driver for a complementary MOSFET array, such as the Supertex DN2625DK6-G. The IC features pulse amplitude modulation with eight-bit resolution and fifteen programmable output level registers. Each level can be programmed to a resolution of +/-127. Its high speed serial-to-parallel interface allows per-scan-line data to be updated quickly for dynamically changing delay times, weighting and waveforms. An apodization digital-to-analog converter smoothes irregularities in the waveforms.
"MD2134 is optimized for delivering high resolution images in high performance, low power, medical diagnostic ultrasound machines," states Stephen Lin, Vice President of Marketing for Supertex. "By utilizing pulse amplitude modulation, MD2134 delivers virtually no propagation delay or time jitter from input to output."
The MD2134 is available in a 40-lead QFN package (MD2134K7-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks. Pricing is US$6.27 each for the MD2134K7-G in 1K quantities.
Supertex, Inc. is a publicly held mixed signal semiconductor manufacturer, focused in high voltage analog and mixed signal products for use in the medical, LED lighting, printer and display, industrial and telecommunication industries.
