LMH6559
www.ti.com SNOSA57C – APRIL 2003 – REVISED MARCH 2013 LMH6559 High-Speed, Closed-Loop Buffer
Check for Samples: LMH6559 FEATURES 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/Ојs the LMH6559 consumes only 10mA
of quiescent current. Total harmonic distortion into a
load of 100Ω at 20MHz is -52dBc. The LMH6559 is
configured internally for a loop gain of one. Input
resistance is 200kΩ and output resistance is but
1.2Ω. 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 0.02В° respectively
at 3.58MHz make the LMH6559 well suited for the
buffering of video signals. 1 2 Closed-Loop Buffer
