GENERAL DESCRIPTION
The AD8007 (single) and AD8008 (dual) are high perfor-
mance current feedback amplifiers with ultralow distortion
and noise. Unlike other high performance amplifiers, the low
price and low quiescent current allow these amplifiers to be
used in a wide range of applications. ADIâs proprietary second
generation eXtra-Fast Complementary Bipolar (XFCB)
process enables such high performance amplifiers with low
power consumption.
The AD8007/AD8008 have 650 MHz bandwidth, 2.7 nV/âHz
voltage noise, â83 dB SFDR @ 20 MHz (AD8007), and â77 dBc
SFDR @ 20 MHz (AD8008).
With the wide supply voltage range (5 V to 12 V) and wide band-
width, the AD8007/AD8008 are designed to work in a variety of
applications. The AD8007/AD8008 amplifiers have a low power
supply current of 9 mA/amplifier.
The AD8007 is available in a tiny SC70 package as well as a
standard 8-lead SOIC. The dual AD8008 is available in both
REV. C
