Beamforming Source Driver From Supertex Excels in Medical Ultrasound Applications

MD2131 Generates High Speed, Arbitrary Waveforms

SUNNYVALE, CA--(Marketwire - Jul 20, 2011) - Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced the MD2131, a high speed, arbitrary waveform push-pull source driver designed for use in diagnostic medical and high intensity, focused ultrasound (HIFU) applications. The IC can also be used in non-destructive image evaluation, metal flaw detection, sonar phase arrays and piezoelectric transducer waveform drivers.

MD2131 consists of CMOS digital logic inputs, an eight-bit digital-to-analog converter and a high speed serial peripheral interface. The output stage of the IC is designed to be the source driver for the Supertex DN2625, a depletion-mode, N-channel, 250V MOSFET. The chipset provides extremely accurate beamforming and focus scanning for diagnostic and therapeutic ultrasound applications.

"MD2131 provides the accuracy with minimal jitter or harmonic distortion that is critical in medical ultrasound applications," states Stephen Lin, Vice President of Marketing for Supertex. "Paired with the Supertex DN2625, the MD2131 excels as a high performance ultrasound beamformer when used with a tightly coupled RF pulsed current transformer."

The MD2131 is available in a 40-lead QFN package (MD2131K7-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 MD2131K7-G in 1K quantities.
