Ultralow Distortion, High Speed Amplifiers
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.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials.
The SO8 SINGLE AMP evaluation board aids in the evaluation of single, 8-lead SOIC operational amplifiers. The SO8 SINGLE AMP evaluation board is a bare board with no components soldered on, which enables users to prototype a variety of operational amplifier circuits. The SO8 SINGLE AMP evaluation board supports any of the Analog Devices, Inc., single operational amplifiers in 8-lead SOIC packages with and without a dedicated feedback pin, an exposed paddle, and an external compensation pin.
The 6-layer evaluation board accepts edge mounted SMA connectors on both inputs and outputs to allow an efficient connection to test equipment and other circuitry.
Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board accepts 0402 or 0603 surface-mount technology (SMT) components, 1206 bypass capacitors, and 100 mil headers.
All components are placed on the primary side. No components are placed on the secondary side.
