GENERAL DESCRIPTION

The AD8007 (single) and AD8008 (dual) are high performance

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. Analog Devices, Inc., 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/√Hz

voltage noise, −83 dB SFDR at 20 MHz (AD8007), and −77 dBc

SFDR at 20 MHz (AD8008).

With the wide supply voltage range (5 V to 12 V) and wide

bandwidth, 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 an

8-lead SOIC and an 8-lead MSOP. These amplifiers are rated to

work over the industrial temperature range of −40°C to +85°C.
