Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 781/329-4700 www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2002 CONNECTION DIAGRAMS 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. ADI’s 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 @ 20 MHz (AD8007), and –77 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 FEATURES Extremely Low Distortion Second Harmonic –88 dBc @ 5 MHz –83 dBc @ 20 MHz (AD8007) –77 dBc @ 20 MHz (AD8008) Third Harmonic –101 dBc @ 5 MHz –92 dBc @ 20 MHz (AD8007) –98 dBc @ 20 MHz (AD8008) High Speed 650 MHz, –3 dB Bandwidth (G = +1) 1000 V/ s Slew Rate Low Noise 2.7 nV/ √Hz Input Voltage Noise 22.5 pA/ √Hz Input Inverting Current Noise Low Power 9 mA/Amplifier Typ Supply Current Wide Supply Voltage Range 5 V to 12 V 0.5 mV Typical Input Offset Voltage Small Packaging SOIC-8, MSOP, and SC70 Packages Available APPLICATIONS Instrumentation IF and Baseband Amplifiers Filters A/D Drivers DAC Buffers 8-lead SOIC and 8-lead MSOP packages.
