Описание

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.
