30 MHz while offering differential gain and phase error of  
0.04% and 0.10. This makes the AD8004 suitable for video  
electronics such as cameras and video switchers.  
–78 dBc THD at 5 MHz  
–61 dBc THD at 20 MHz  
High Output Current of 50 mA  
Available in a 14-Lead PDIP, SOIC, and CERDIP  
The AD8004 offers low power of 3.5 mA/amplifier and can run  
on a single +4 V to +12 V power supply, while being capable of  
delivering up to 50 mA of load current. All this is offered in a  
small 14-lead DIP or 14-lead SOIC package. These features  
make this amplifier ideal for portable and battery powered appli-  
cations where size and power are critical.  
APPLICATIONS  
Image Scanners  
Active Filters  
Video Switchers  
Special Effects  
The outstanding bandwidth of 250 MHz along with 3000 V/ms  
of slew rate make the AD8004 useful in many general-purpose,  
high speed applications where dual power supplies of up to ±6 V  
and single supplies from 4 V to 12 V are needed. The AD8004  
is available in the industrial temperature range of –40C to +85C  
in the N and R packages, and in the military temperature range  
of –55C to +125C in the Q package.  
GENERAL DESCRIPTION  
The AD8004 is a quad, low power, high speed amplifier designed  
to operate on single or dual supplies. It utilizes a current feed-  
back architecture and features high slew rate of 3000 V/ms  
making the AD8004 ideal for handling large amplitude pulses.  
Additionally, the AD8004 provides gain flatness of 0.1 dB to
