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 -- HV2661 and
HV2761. 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 ICs are configured as eight three-to-one multiplexer and
feature an operating voltage up to 200V, which enables deeper body
tissue imaging capability in ultrasound applications. Low quiescent
power dissipation of 10uA ensures highly efficient operation and 18
ohm switch resistance minimizes signal attenuation, resulting in
clearer images.
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 HV2761 also features
integrated bleed resistors to discharge residual DC voltages and
reduce erroneous signals.
The HV2661 and HV2761 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. These ICs deliver high resolution
imaging and high channel density for greater performance in less
board space.
The HV2661 and the HV2761 are available in RoHS compliant
48-Lead LQFP packaging (HV2661FG-G and HV2761FG-G). Samples are
available from stock. Lead-time for production quantities is 4-6
weeks ARO. Pricing is US$10.52 each for the HV2661FG-G and
HV2761FG-G, in 1K quantities.
