The LMH6554 device 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 TIs 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 sacrificing response flatness, bandwidth, harmonic distortion, or
output noise performance.
The low-impedance differential output of the device is designed to drive ADC inputs and
any intermediate filter stage. The LMH6554 delivers 16-bit linearity up to 75 MHz when driving 2-V
peak-to-peak into loads as low as 200 Ω.
The LMH6554 is fabricated in TIs advanced complementary BiCMOS process and is available
in a space-saving 14-lead UQFN package for higher performance.
