Quad Channel Transmit/Receive Switch From Supertex Offers Design Flexibility 
for Medical Ultrasound Systems 
MD0200 With Multiplex Functionality to Enable Design Flexibility for
Image Quality Enhancement 
SUNNYVALE, CA -- (Marketwired) -- 11/19/13 --   Supertex (NASDAQ:
SUPX), a recognized leader in high voltage analog and mixed signal
integrated circuits (ICs), today introduced the MD0200, a high
voltage four-channel T/R switch with a low voltage analog multiplex
designed for medical ultrasound imaging applications.  
The MD0200 consists of four +/-130V T/R switches followed by four low
voltage analog switches with a serial logic controlled interface. The
only supply voltage needed is 5V for the logic control. The device
features a typical T/R switch resistance of 17 ohms for low insertion
loss. Once the T/R switch detects a voltage magnitude greater than
+/-1.0V, it will automatically start to turn off. In the off state,
the T/R switch can withstand up to +/-130V to protect the inputs of
the low noise receivers. A low voltage multiplexer is included to
enable users the flexibility to route the echo signals to different
receivers to optimize the image. 
"As medical diagnostic ultrasound systems are constantly trying to
improve image quality, Supertex remains committed to providing
innovative products to ultrasound equipment manufacturers to reach
their goals," states Jimes Lei, Director of Application Engineering
of Supertex. "The MD0200 topology provides additional system design
flexibility on the receiver side for image quality enhancement." 
The MD0200 is available in a lead(Pb)-free/RoHS compliant 18-lead 5x5
DFN package (MD0200K6-G). Samples are available from stock. Lead-time
for production quantities is 4-6 weeks, ARO. Pricing is US$6.40 each
in 1K quantities.
