The ADA4856-3 (triple) is a fixed gain of +2, single-supply, rail-

to-rail output video amplifier. It provides excellent video

performance with 225 MHz, −3 dB bandwidth, 800 V/μs slew rate,

and 74 MHz, 0.1 dB flatness into a 150 Ω load. It has a wide

input common-mode voltage range that extends 0.2 V below

ground and 1 V below the positive rail. In addition, the output

voltage swings within 200 mV of either supply, making this video

amplifier easy to use on single-supply voltages as low as 3.3 V.

OUT

The ADA4856-3 offers a typical low power of 7.8 mA per amplifier,

while being capable of delivering up to 52 mA of load current.

It also features a power-down function for power sensitive

applications that reduces the supply current to 1 mA.
