NATIONAL Semiconductor, represented by Arrow Electronics , has launched two new high-speed LMH buffer amplifiers that increase bandwidth and minimise distortion for high-performance video applications.
Derived from National's 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 0.02 degrees differential phase, 0.06% gain, and ultra-high slew rates, these buffer amplifiers integrate National's strengths in analogue design, process technology, and reliable manufacturing.
National's LMH6559 is a single, high-speed, closed-loop buffer amplifier with 1.75GHz bandwidth, ultra-high slew rate (4580V/μs), 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/μs), and low differential phase and gain, which minimise 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 analogue multiplexing, high-density buffering, and test equipment.
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 utilises deep trench technology on a bonded wafer for optimal high-speed amplifier performance.
