AD810AN

The AD810 is a composite and HDTV-compatible, current
feedback, video operational amplifier, ideal for use in systems
such as multimedia, digital tape recorders, and video cameras.
The 0.1 dB flatness specification at a bandwidth of 30 MHz
(G = 2) and the differential gain and phase of 0.02% and 0.04?
(NTSC) make the AD810 ideal for any broadcast quality video
system. All these specifications are under load conditions of
150 ? (one 75 ? back terminated cable).
The AD810 is ideal for power sensitive applications such as
video cameras, offering a low power supply current of 8.0 mA
maximum. The disable feature reduces the power supply
current to only 2.1 mA, while the amplifier is not in use, to
conserve power. Furthermore, the AD810 is specified over a
power supply range of ?5 V to ?15 V.
The AD810 works well as an ADC or DAC buffer in video
systems due to its unity gain (G = 1) ?3 dB bandwidth of
80 MHz. Because the AD810 is a transimpedance amplifier, this
bandwidth can be maintained over a wide range of gains while
featuring a low noise of 2.9 nV/?Hz for wide dynamic range
applications.
