LMH6559
High-Speed, Closed-Loop Buffer
General DescriptionThe LMH6559isa high-speed, closed-loop buffer designed
for applications requiring the processingof very high fre-
quency signals. While offeringa small signal bandwidthof
1750MHz, andan ultra high slew rateof 4580V/µs the
LMH6559 consumes only 10mAof quiescent current. Total
harmonic distortion intoa loadof 100Ωat 20MHzis −52dBc.
The LMH6559is configured internallyfora loop gainof one.
Input resistanceis 200kΩ and output resistanceisbut 1.2Ω.
These characteristics makethe LMH6559an ideal choicefor
the distributionof high frequency signalson printed circuit
boards. Differential gain and phase specificationsof 0.06%
and 0.02˚ respectivelyat 3.58MHz makethe LMH6559 well
suitedforthe bufferingof video signals.
The deviceis fabricatedon National’s high-speed VIP10
process using National’s proven high performance circuit
architectures.
