The dual AD8008 is available in both an The AD8007 (single) and AD8008 (dual) are high performance 8-lead SOIC and an 8-lead MSOP. These amplifiers are rated to current feedback amplifiers with ultralow distortion and noise. work over the industrial temperature range of 40C to +85C. Unlike other high performance amplifiers, the low price and 30 low quiescent current allow these amplifiers to be used in a G = +2 R = 150 L wide range of applications. Analog Devices, Inc., proprietary 40 V = 5V S V = 2V p-p second-generation eXtra-Fast Complementary Bipolar (XFCB) OUT 50 process enables such high performance amplifiers with low power consumption. 60 The AD8007/AD8008 have 650 MHz bandwidth, 2.7 nV/Hz 70 voltage noise, 83 dB SFDR at 20 MHz (AD8007), and 77 dBc SECOND 80 SFDR at 20 MHz (AD8008). 90 With the wide supply voltage range (5 V to 12 V) and wide bandwidth, the AD8007/AD8008 are designed to work in a THIRD 100 variety of applications. The AD8007/AD8008 amplifiers have 110 a low power supply current of 9 mA/amplifier. 111000 FREQUENCY (MHz) Figure 4. AD8007 Second and Third Harmonic Distortion vs. Frequency Rev.
