FEATURES

DESCRIPTION

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

•

Closed-Loop Buffer

designed for applications requiring the processing of

1750MHz Small Signal Bandwidth

very high frequency signals. While offering a small

signal bandwidth of 1750MHz, and an ultra high slew

rate of 4580V/

load of 100

Ω at 20MHz is −52dBc. The LMH6559 is

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
