Supertex Announces a New High Voltage MEMS Driver and Its Strategy of Expanding 
Focus on MEMS Interface Solutions 
HV264 Quad 200V Amplifier Array for High Voltage Drive Applications 
SUNNYVALE, CA -- (Marketwired) -- 04/24/13 --  Supertex (NASDAQ:
SUPX), a recognized leader in high voltage analog and mixed signal
integrated circuits (ICs), today announced, as a part of its future
business strategy, the intent to provide greater focus and support to
the Micro-Electro-Mechanical System (MEMS) marketplace. The Company
considers the growing MEMS market and its applications to be a
critical focus for application of the Company's unique system and
processing expertise. As part of this new strategy, Supertex released
the new HV264 Quad High Voltage Amplifier Array. 
MEMS applications continue to evolve and have an ever increasing
impact on products and our daily lives in most major electronics
markets, from high reliability, optical datacom, and medical, to
industrial and consumer. Supertex is expanding its standard and
custom product development to drive MEMS solutions. Supertex will
increase its driver products for optical switching applications, as
well as expand into a broader range of MEMS solutions. Our products
will find use in communications, diagnostics and analysis,
manufacturing, fabrication, and more. 
The HV264 will find use in a variety of MEMS and other High Voltage
Drive applications, such as driving optical MEMS and piezoelectric
transducers. Versus the large amplifier array of most available
solutions, the base of 4 amplifiers offers significant advantages in
design layout and modularization to engineers tackling the large mix
of applications for MEMS and Piezoelectric solutions. Some areas of
application are MEMs micromirror drives as seen in optical networking
and communications, test and measurement, printing, component
alignment, 3D position tracking and positioning such as for gaming,
laser marking, small and transparent displays, biomedical
instrumentation and imaging, and more. Potential piezoelectric
applications include security sensors, fluid measurement, and more.  
The four channels of the HV264 consist of four independent high
voltage amplifiers, capable of inverting or non-inverting
configurations. The outputs can swing at 9V/us, measured
 with a 200V
supply and a 15pF load. The HV264 operates with a 200V and a 5V
supply. With an integrated high value gain setting resistor for
internal feedback (66.7V/V), no external passives for feedback are
needed. Internal voltage swing is designed to proceed between 50mV
and 2.85V on the input, with the output ranging from 3.33V to Vpp -
10V (the dc supply voltage minus 10V.) 
Supertex has been a key supplier of solutions in this space, and the
Company is working to expand its relationship with other key MEMS
suppliers. Supertex will continue to improve its unique process
capabilities, and provide increasing levels of service and value to
its base of MEMS customers.  
Samples of HV264TS-G are available from stock in a Pb(free)/RoHS
compliant 24-Lead TSSOP package. Lead-time for production quantities
is 4 - 6 weeks, ARO. The HV264TS-G is priced at USD$6.16 each for 1K
quantities. The HV264DB1 demo board is also available for evaluation.
HV264 is a derivative chip of the MEMS driver family which includes
HV254, HV256 and HV257, all of which contain 32 channels. These
