GENERAL DESCRIPTION

A wideband current feedback operational amplifier, the AD811 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 ?) make the AD811 an excellent choice for all video systems. The AD811 is designed to meet a stringent 0.1 dB gain flatness specification to a band width of 35 MHz (G = +2) in addition to low differential gain and phase errors. This performance is achieved whether driving one or two back-terminated 75 ? cables, with a low power supply current of 16.5 mA. Furthermore, the AD811 is specified over a power supply range of ±4.5 V to ±18 V. (Continued on page 3)
