APPLICATIONS

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

+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.

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 Ω)

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 outstanding bandwidth of 145 MHz along with 1600 V/µs

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.
