General Description

The LMH6559 is a high-speed, closed-loop buffer designed for applications requiring the processing of very high frequency signals. While offering a small signal bandwidth of 1750MHz, and an ultra high slew rate of 4580V/µs the LMH6559 consumes only 10mA of quiescent current. Total harmonic distortion into a load of 100 at 20MHz is -52dBc. The LMH6559 is configured internally for a loop gain of one. Input resistance is 200k and output resistance is but 1.2. These characteristics make the LMH6559 an ideal choice for the distribution of high frequency signals on printed circuit boards. Differential gain and phase specifications of 0.06% and 0.02° respectively at 3.58MHz make the LMH6559 well suited for the buffering of video signals.

The device is fabricated on National's high-speed VIP10 process using National's proven high performance circuit architectures.
