LMH6559

High-Speed, Closed-Loop Buffer

General Description

Features

n Closed-loop buffer

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 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 0.02˚ respectively at 3.58MHz make the LMH6559 well

suited for the buffering of video signals.
