DESCRIPTION

The LMH6559 is a high-speed, closed-loop buffer

designed for applications requiring the processing of

very high frequency 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.

The device is fabricated on Texas Instruments' high•

speed VIP10 process using TI's proven high

performance circuit architectures.
