LMH6559
High-Speed, Closed-Loop Buffer
General Description
The LMH6559 is a high-speed, closed-loop buffer designed
for applications requiring the processing of very high fre-
quency 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.
