Product Summary

The AD811AN is a wideband current-feedback operational amplifier, optimized for broadcast quality video systems. The –3 dB bandwidth of 120 MHz at a gain of +2 and differential gain and phase of 0.01% and 0.01° (RL = 150 W) make the AD811AN an excellent choice for all video systems. The AD811AN is designed to meet a stringent 0.1 dB gain flatness specification to a bandwidth of 35 MHz (G = +2) in addition to the low differential gain and phase errors. This performance is achieved whether driving one or two back terminated 75 W cables, with a low power supply current of 16.5 mA. Furthermore, the AD811AN is specified over a power supply range of ±4.5 V to ±18 V. The applications of the AD811AN include Video Crosspoint Switchers, Multimedia Broadcast Systems, HDTV Compatible Systems, Video Line Drivers, Distribution Amplifiers, ADC/DAC Buffers, DC Restoration Circuits, Medical—Ultrasound, PET, Gamma and Counter Applications.
