Cirrus Logic Drives Piezoelectric Market With New Levels of Performance In Two New Single Package Solutions
September 29 2009 - 9:00AM
Business Wire
Cirrus Logic Inc. (Nasdaq: CRUS) has delivered new levels of
performance for the piezoelectric driver market with the addition
of the PA107DP and MP103FC high-voltage, high-speed power
amplifiers to its Apex Precision Power® product family. The PA107DP
is capable of slew rates up to 3000 V/µs, which raises the bar for
single-package hybrids. The MP103FCFC is a new dual-channel
designed hybrid that can deliver a very high 15 A X 2 of output
current. Both devices are operational with voltage supplies of up
to 200 V.
The PA107DP is an attractive option for driving piezos used in
medical imaging and ultrasound applications, as well as
programmable power supplies for the ATE market, because the high
slew rate increases voltage response time. The end result is
greater accuracy and rapid delivery of voltage throughout the end
system, enabling imaging scans that take less time to complete and
power supplies that cycle with greater efficiency, for example.
Customers needing higher speed will select the PA107DP because it
extends the available slew rate performance within the Apex
Precision Power product family by 3X that of the PA85, which
features a 1000 V slew rate. The PA107DP also improves output
current performance with 1.5 A/5 A PEAK, and a high-gain bandwidth
of 180 MHz. The device is housed in a 12-pin Power SIP package that
requires less than two square inches of board space.
“Through the Apex Precision Power brand of products, Cirrus
Logic has a long history of innovation in the piezo drive market
for high-voltage, high-speed products,” said Greg Brennan, vice
president and general manager, Cirrus Logic Apex Precision Power
business unit. “We continue to see rapid acceptance of
off-the-shelf piezo drive technology in new market segments, such
as medical imaging, where larger discrete solutions have been more
typical. With the introduction of the PA107DP and MP103FC, we
continue to expand the performance parameters of single-packaged IC
and hybrid piezo drivers that can be easily retrofitted into
existing systems or prototyped for next generation designs.”
The MP103FC is a dual-channel device that allows designers to
save significant board space in multichannel systems. The device
features up to 15 A of output current per channel, operating
voltages ranging from 30 V up to 200 V and a slew rate of 180 V per
microsecond. The targeted application for the MP103FC is driving
piezo print heads in large format industrial ink jet printers
typically used to produce wide format banners and billboards.
The MP103FC uses the industrial temperature range “open frame”
packaging form factor developed for a number of Apex Precision
Power products to offer a lower per unit cost, in comparison with a
hermetically sealed hybrid, while still providing very high levels
of performance.
