New Twenty-Four-Channel Analog Switches Increase Density of Medical Ultrasound Circuit Boards

HV2662 and HV2762 Deliver High Resolution Medical Ultrasound Images

SUNNYVALE, CA--(Marketwire - Jun 23, 2011) - Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced two new high voltage, twenty-four-channel analog switches -- HV2662 and HV2762. They are optimized for use in applications that require high voltage switching which is controlled by low voltage signals, as is commonly found in diagnostic medical ultrasound imaging, as well as in piezoelectric transducer drivers and printers. The parts are available in LFGA and BGA packaging.

The outputs of both ICs are configured as two sets of 24 single pole, single throw, analog switches that feature low typical on-resistance of 18 ohms. This low switch resistance minimizes signal attenuation in the receive mode and provides two amp current capability in the transmit mode.

Both ICs may be utilized with multiple combinations of high voltage supplies to accommodate different operating modes in diagnostic medical ultrasound imaging, such as +40V/-160V, +100V/-100V, +160V/-40V (Vpp/Vnn). The HV2762 also features integrated bleed resistors to discharge residual DC voltages and reduce erroneous signals.

"The HV2662 and HV2762 combine Supertex's proven expertise in high voltage analog signal control with our proprietary HVCMOS technology to produce very efficient analog switches for diagnostic medical ultrasound applications," states Stephen Lin, Vice President of Marketing for Supertex. "These ICs deliver high resolution imaging and high channel density for greater performance in less board space."

The HV2662 and the HV2762 are available in 64-pad LFGA packages (HV2662LA-G and HV2762LA-G) and 64-ball LFGA packages (HV2662LB-G and HV2762LB-G). All parts are RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$14.44 each for the HV2662LA-G, US$14.46 each for the HV2662LB-G, US$14.56 each for the HV2762LA-G and US$14.59 each for the HV2762LB-G, all in 1K quantities.
