PRODUCT DESCRIPTION

The AD812 is a low power, single supply, dual video amplifier.

Each of the amplifiers have 50 mA of output current and are

optimized for driving one back-terminated video load (150 )

each. Each amplifier is a current feedback amplifier and fea-

tures gain flatness of 0.1 dB to 40 MHz while offering differen-

tial gain and phase error of 0.02% and 0.02 . This makes the

AD812 ideal for professional video electronics such as cameras

and video switchers.

The AD812 offers low power of 4.0 mA per amplifier max (V

+5 V) and can run on a single +3 V power supply. The outputs

of each amplifier swing to within one volt of either supply rail to

easily accommodate video signals of 1 V p-p. Also, at gains of

+2 the AD812 can swing 3 V p-p on a single +5 V power sup-

ply. All this is offered in a small 8-lead plastic DIP or 8-lead

SOIC package. These features make this dual amplifier ideal

for portable and battery powered applications where size and

power is critical.

The outstanding bandwidth of 145 MHz along with 1600 V/ s

of slew rate make the AD812 useful in many general purpose

high speed applications where a single +5 V or dual power sup-

plies up to 15 V are available. The AD812 is available in the

industrial temperature range of –40 C to +85 C.
