LMH6560
Quad, High-Speed, Closed-Loop Buffer
General Description
The LMH6560 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
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 100
at
20MHz is 51dBc. The LMH6560 is configured internally for
a loop gain of one. Input resistance is 100k
and output
resistance is but 1.5
. 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 specifica-
tions of 0.10% and 0.03 respectively at 3.58MHz make the
LMH6560 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.
