APPLICATIONS  
The AD812 offers low power of 4.0 mA per amplifier max (VS =  
+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.
