PRODUCT DESCRIPTION
The AD8005 is an ultralow power, high-speed amplifier with a
wide signal bandwidth of 170 MHz and slew rate of 280 V/
μ
s.
This performance is achieved while consuming only 400
μ
A of
quiescent supply current. These features increase the operating
time of high-speed battery-powered systems without reducing
dynamic performance.

Current Feedback Amplifier
The current feedback design results in gain flatness of 0.1 dB
to 30 MHz while offering differential gain and phase errors of
0.11% and 0.4
°
. Harmonic distortion is low over a wide
bandwidth with THDs of –63 dBc at 1 MHz and –50 dBc at
10 MHz. Ideal features for a signal conditioning amplifier or
buffer to a high-speed A-to-D converter in portable video,
medical or communication systems.
The AD8005 is characterized for +5 V and
±
5 V supplies and
will operate over the industrial temperature range of –40
°
C to
+85
°
C. The amplifier is supplied in 8-lead plastic DIP, 8-lead
SOIC and 5-lead SOT-23 packages.
