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
â40 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
â38 dBc SFDR.
The AD8009 is available in a small SOIC package and will
operate over the industrial temperature range â40°C to +85°C.
