DESCRIPTION

The LMH6555 is an ultra high speed differential line

driver with 53 dB SFDR at 750 MHz. The LMH6555

features a fixed gain of 13.7 dB. An input to the

device allows the output common mode voltage to be

set independent of the input common mode voltage in

order to simplify the interface to high speed

differential input ADCs. A unique architecture allows

the device to operate as a fully differential driver or as

a single-ended to differential converter.

The outstanding linearity and drive capability (100Ω

differential load) of this device are a perfect match for

driving high speed analog-to-digital converters. When

combined with the ADC081000/ ADC081500 (single

or dual ADC), the LMH6555 forms an excellent 8-bit data acquisition system with analog bandwidths

exceeding 750 MHz.

The LMH6555 is offered in a space saving 16-pin

WQFN package.
