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 SOIC
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 SOIC package. These features make this
amplifier ideal for portable and battery powered applications
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,
GENERAL DESCRIPTION
high speed applications where dual power supplies of up to ±6 V
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
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 R package.
