LMH6555

Low Distortion 1.2 GHz Differential Driver

General Description

Features

The LMH6555 is an ultra high speed differential line driver

with 50 dB SFDR at 750 MHz. The LMH6555 features a fixed

gain of 13.6 dB. An input to the device allows the output com-

mon mode voltage to be set independent of the input common

mode voltage in order to simplify the interface to high speed

differential input ADC’s . A unique architecture allows the de-

vice to operate as a fully differential driver or as a single-

ended to differential converter.

Typical Unless Otherwise Specified:

−3 dB bandwidth (V_OUT= 0.80_PP

±0.5 dB gain flatness (V_OUT= 0.80 V_PP

The outstanding linearity and drive capability (100Ω differen-

tial load) of this device is a perfect match for driving high

speed analog-to-digital converters. When combined with the

ADC081000/ ADC08D1500, the LMH6555 forms an excellent

8-bit data acquisition system with analog bandwidths exceed-

ing 1 GHz.
