FEATURES

DESCRIPTION

The LMH6554 is a high performance fully differential

2

•

Small Signal Bandwidth 2.8 GHz

amplifier designed to provide the exceptional signal

•

fidelity and wide large-signal bandwidth necessary for

•

0.1 dB Gain Flatness 830 MHz

driving 8 to 16 bit high speed data acquisition

systems. Using TI’s proprietary differential current

•

OIP3 @ 150 MHz 46.5 dBm

mode input stage architecture, the LMH6554 has

•

HD2/HD3 @ 75 MHz -96 / -97 dBc

unity gain, small-signal bandwidth of 2.8 GHz and

•

Input Noise Voltage 0.9 nV/

√Hz

allows operation at gains greater than unity without

sacrificing response flatness, bandwidth, harmonic

•

Input Noise Current 11 pA/

√Hz
