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/ s.

This performance is achieved while consuming only 400 A of

quiescent supply current. These features increase the operating

time of high-speed battery-powered systems without reducing

dynamic performance.

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

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.
