Product Summary

The ad811anz is a wideband current feedback operational amplifier, the ad811anz is optimized for broadcast-quality video systems. The −3 dB bandwidth of 120 MHz at a gain of +2 and the differential gain and phase of 0.01% and 0.01° (RL = 150 Ω) make the ad811anz is an excellent choice for all video systems. The ad811anz is designed to meet a stringent 0.1 dB gain flatness specification to a bandwidth of 35 MHz (G = +2) in addition to low differential gain and phase errors. Application areas of the ad811anz include Video crosspoint switchers, multimedia broadcast systems, HDTV compatible systems, Video line drivers, distribution amplifiers, ADC/DAC buffers, DC restoration circuits.
