FEATURES
DESCRIPTION
The LMH™6560 is a high speed, closed-loop buffer
23
•
Closed-Loop Quad Buffer
680MHz Small Signal Bandwidth
3100V/μs Slew Rate
designed for applications requiring the processing of
very high frequency signals. While offering a small
signal bandwidth of 680MHz, and a very high slew
rate of 3100V/μs the LMH6560 consumes only 46mA
of quiescent current for all four buffers. Total
harmonic distortion into a load of 100Ω at 20MHz is
−51dBc. The LMH6560 is configured internally for a
loop gain of one. Input resistance is 100kΩ and
output resistance is but 1.5Ω. Crosstalk between the
buffers is only −55dB. These characteristics make the
LMH6560 an ideal choice for the distribution of high
frequency signals on printed circuit boards.
Differential gain and phase specifications of 0.10%
and 0.03° respectively at 3.58MHz make the
LMH6560 well suited for the buffering of video
signals.
