The LMH6554 is a high performance fully differential amplifierdesigned to provide the exceptional signal fidelity and widelarge-signal bandwidth necessary for driving 8 to 16 bit highspeed data acquisition systems. Using National’s proprietarydifferential current mode input stage architecture, theLMH6554 allows operation at gains greater than unity withoutsacrificing response flatness, bandwidth, harmonic distortion,or output noise performance.
