Replacement verdict
Not a drop-in replacement
The AD8009AR and AD8002AR-REEL are not drop-in replacements for each other. The AD8009AR is a single-channel current-feedback amplifier optimized for very high slew rate and bandwidth, while the AD8002AR-REEL is a dual-channel voltage-feedback amplifier. They differ in channel count, amplifier topology, package pinout, and typical application role, so substituting one for the other requires circuit redesign and validation.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009AR | AD8002AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | A single vs dual channel count determines board layout, package footprint, and whether one part can replace the other in a given circuit. |
| -3 dB Bandwidth | 1 GHz | 600 MHz | Bandwidth defines the maximum signal frequency the amplifier can handle, directly affecting high-speed signal fidelity and substitutability. |
| Slew Rate | 5500 V/µs | 1200 V/µs | Slew rate limits how fast the output can respond to large signal swings; a lower slew rate part may distort fast transients. |
| Supply Voltage Range | ±5 V to ±6 V (10 V to 12 V) | ±5 V to ±15 V (10 V to 30 V) | The allowable supply range determines compatibility with the system power rails and headroom available for the signal. |
| Quiescent Supply Current | 16 mA | 14 mA | Quiescent current affects power budget and thermal design, which matters when swapping parts in power-sensitive designs. |
| Input Voltage Noise | 1.1 nV/√Hz | 2 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal applications, so a noisier substitute may degrade performance. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package compatibility determines whether the part can be physically placed on the same PCB footprint. |
| Output Current | 175 mA | 70 mA | Output drive capability affects the ability to drive low-impedance loads such as cables or ADCs, influencing direct substitutability. |

Frequently asked questions
What are the primary differences between the AD8009AR and AD8002AR-REEL?
The AD8009AR is a single, high-speed current feedback amplifier offered in an 8-lead SOIC package, while the AD8002AR-REEL is a dual current feedback amplifier supplied in an 8-lead SOIC package on tape and reel. The AD8009 is optimized for very high slew rate and large signal bandwidth, whereas the AD8002 integrates two amplifiers in one package for dual-channel designs.
Are the AD8009AR and AD8002AR-REEL pin-compatible?
No. Although both use an 8-lead SOIC package, the AD8009AR is a single amplifier with a different pin function assignment than the AD8002AR-REEL, which is a dual amplifier. Pin functions and internal connections differ, so they are not direct drop-in replacements.
What are the key dynamic specifications of the AD8009AR?
The AD8009AR is specified with a -3 dB bandwidth of approximately 1 GHz (G = +1), a slew rate of about 5500 V/µs, and a settling time of 10 ns to 0.1%. These parameters make it suitable for high-speed signal processing and pulse applications.
What are the key dynamic specifications of the AD8002AR-REEL?
The AD8002AR-REEL dual amplifier offers a -3 dB bandwidth of approximately 600 MHz (G = +1) per amplifier and a slew rate of about 2000 V/µs per amplifier. It is intended for dual-channel video and communication signal chains where two matched amplifiers are required.
Can the AD8009AR and AD8002AR-REEL operate from the same supply voltages?
Both devices are specified for operation on dual supplies of ±5 V and single supplies of +5 V to +12 V, subject to the limits stated in the respective manufacturer datasheets. Designers should verify the exact supply range and quiescent current for each part before finalizing the power design.
Why is the AD8002AR-REEL supplied on tape and reel?
The -REEL suffix indicates the AD8002AR-REEL is packaged in tape-and-reel format for automated pick-and-place assembly. This packaging is intended for high-volume production and does not change the electrical specifications of the dual amplifier.
Which part should be selected for a dual-channel high-speed design?
The AD8002AR-REEL is the appropriate choice when two matched current feedback amplifiers are needed in a single package, reducing board area and component count. The AD8009AR is selected when a single amplifier with higher slew rate and bandwidth is required.
