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

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.
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.
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
±6V
and single supplies from 4 V to 12 V are needed. The AD8004
is available in the industrial temperature range of –40
∞C to +85∞C
in the N and R packages, and in the military temperature range
of –55
∞C to +125∞C in the Q package.
