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° (R
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 Ω 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.
