National's LMH6559 is a single, high-speed, closed-loop buffer amplifier with 1.75 GHz bandwidth, ultrahigh 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 aimed at 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 minimise video degradation.
Additional features include guaranteed single-supply operation from 3 to 10V and high output current (74mA).
The LMH6560 is targeted for multichannel 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.
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 1000-unit quantities.
