PRODUCT DESCRIPTION  
The AD8009 is an ultrahigh speed current feedback amplifier  
with a phenomenal 5,500 V/µs slew rate that results in a rise  
time of 545 ps, making it ideal as a pulse amplifier.  
The high slew rate reduces the effect of slew rate limiting and  
results in the large signal bandwidth of 440 MHz required for  
high resolution video graphic systems. Signal quality is main-  
tained over a wide bandwidth with worst case distortion of  
–40 dBc @ 250 MHz (G = +10, 1 V p-p). For applications  
with multitone signals such as IF signal chains, the third order  
Intercept (3IP) of 12 dBm is achieved at the same frequency.  
This distortion performance coupled with the current feedback  
architecture make the AD8009 a flexible component for a gain  
stage amplifier in IF/RF signal chains.  
The AD8009 is capable of delivering over 175 mA of load  
current and will drive four back terminated video loads while  
maintaining low differential gain and phase error of 0.02% and  
0.04° respectively. The high drive capability is also reflected in  
the ability to deliver 10 dBm of output power @ 70 MHz with  
–38 dBc SFDR.

The AD8009 is available in a small SOIC package and will  
operate over the industrial temperature range –40°C to +85°C.
