Overview

  • 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/μs slew rate
  • Low noise
    2.7 nV/√Hz input voltage noise
    22.5 pA/√Hz input inverting current noise
  • Low power: 9 mA/amplifier typical supply current
  • Wide supply voltage range: 5 V to 12 V
  • 0.5 mV typical input offset voltage
  • Small packaging: 8-lead SOIC, 8-lead MSOP, and 5-lead SC70

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.

Tools & Simulations

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.

Open Tool

Analog Photodiode Wizard

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
