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.

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.
