2.8 GHz Ultra Linear Fully Differential Amplifier
General Description
The LMH6554 is a high performance fully differential amplifier
designed to provide the exceptional signal fidelity and wide
large-signal bandwidth necessary for driving 8 to 16 bit high
speed data acquisition systems. Using National’s proprietary
differential current mode input stage architecture, the
LMH6554 has unity gain, small-signal bandwidth of 2.8 GHz
and allows operation at gains greater than unity without sac-
rificing response flatness, bandwidth, harmonic distortion, or
output noise performance.
The device's low impedance differential output is designed to
drive ADC inputs and any intermediate filter stage. The
LMH6554 delivers 16-bit linearity up to 75 MHz when driving
2V peak-to-peak into loads as low as 200Ω.
The LMH6554 is fabricated in National Semiconductor’s ad-
vanced complementary BiCMOS process and is available in
a space saving, thermally enhanced 14 lead LLP package for
higher performance.
