New High-Speed Buffer Amplifiers from National Semiconductor Offer Low Differential Phase and Gain Specifications Critical for Video Applications

May 12, 2003

May 12, 2003 - National Semiconductor Corporation (NYSE:NSM) today launched two new high-speed LMH buffer amplifiers that increase bandwidth and minimize distortion for high-performance video applications.  Derived from National's unique VIP10 process technology, these amplifiers are designed for applications in test equipment, video switching and routing, medical imaging, professional video cameras and other high-performance applications.  Offering excellent differential phase (0.02 degrees) and gain (0.06%) and ultra-high slew rates, these buffer amplifiers integrate National's strengths in analog design, process technology, reliable manufacturing and price/performance leadership.

"With these new buffer amplifiers, we're increasing National's ability to deliver high-performance products for a variety of markets," said Erroll Dietz, product line director for National's Amplifier product group.  "With features that increase bandwidth, minimize distortion and provide outstanding differential phase and gain, these products are ideally suited for the video market.  Our entire portfolio of LMH products leverages National's strength in manufacturing and our VIP10 process technology, allowing us to deliver the best price/performance ratio on the market."

National's LMH6559 is a single, high-speed, closed-loop buffer amplifier with 1.75 GHz bandwidth, ultra-high slew rate (4580V/us), 0.02 degrees differential phase and 0.06% differential gain.  It has the highest small signal bandwidth and is the fastest single, closed-loop buffer on the market.  Additionally, the LMH6559 offers low distortion (-52dBc at 20MHz) and high output current (74mA).  It is targeted for video switching and routing, high-frequency active filters and wideband DC clamping buffers.

National's LMH6560 is a quad, high-speed, closed-loop buffer amplifier with a high slew rate (3100V/us), and low differential phase and gain, which minimize video degradation.  Additional features include guaranteed single supply operation from 3V to 10V and high output current (74mA).  The LMH6560 is targeted for multi-channel video distribution, high-speed analog multiplexing, high-density buffering, and test equipment.

VIP10 Process
National's latest LMH buffer amplifiers are members of a new series of high-speed products based upon the VIP10 process.  Developed in National's wafer fabrication site in Arlington, Texas, VIP10 is a high speed, complementary bipolar IC process that utilizes deep trench technology on a bonded wafer for optimal high-speed amplifier performance. 

Pricing and Availability
National's LMH6559, available now in SOIC-8 and SOT23-5 packaging, is priced at $1.39.  The LMH6560, available now in SOIC-14 and TSSOP-14 packaging, is priced at $3.35.  All prices are for 1,000-unit quantities.  For more information on National's LMH6559 and LMH6560, visit http://www.national.com/pf/LM/LMH6559.html and http://www.national.com/pf/LM/LMH6560.html
