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 sacrificing 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 advanced complementary BiCMOS process and is available in a space saving, thermally enhanced 14 lead LLP package for higher performance. Applications • Differential ADC driver • Single-ended to differential converter • High speed differential signaling • IF/RF and baseband gain blocks • SAW filter buffer/driver • Oscilloscope Probes • Automotive Safety Applications • Video over twisted pari • Differential line driver
