Replacement verdict
Compatible functional replacement candidate
The AD8009AR and AD8001AR-REEL are both high-speed current-feedback operational amplifiers from Analog Devices in the same 8-lead SOIC package, sharing a common functional architecture and supply framework. However, they differ in key dynamic performance metrics such as bandwidth, slew rate, and quiescent current, so the AD8009AR can serve as a functional substitute for the AD8001AR-REEL only after the system's AC performance and power budget are validated against the target application requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009AR | AD8001AR-REEL | Why it matters |
|---|---|---|---|
| -3 dB Bandwidth | 1 GHz (G = +2) | 800 MHz (G = +2) | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain, directly affecting high-speed signal fidelity. |
| Slew Rate | 5500 V/µs | 1200 V/µs | Slew rate limits how fast the output can respond to large signal swings; higher slew rate supports faster large-signal transitions and reduces distortion. |
| Supply Voltage Range | ±5 V to ±6 V (dual) | ±3 V to ±6 V (dual) | The allowable supply range determines compatibility with the system power rails and headroom available for signal swing. |
| Supply Current per Amplifier | 16 mA typ | 5.5 mA typ | Quiescent current affects power consumption and thermal budget, which is critical in dense or power-sensitive designs. |
| Input Voltage Noise | 1.1 nV/√Hz | 2.5 nV/√Hz | Lower input voltage noise improves the signal-to-noise ratio for small-signal amplification, especially in low-noise front-end designs. |
| Input Offset Voltage | 2 mV max | 5 mV max | Offset voltage introduces DC error at the output; lower offset improves accuracy in precision DC-coupled applications. |
| Output Current | 175 mA | 70 mA | Output drive capability determines the ability to drive low-impedance loads such as cables or ADCs without significant distortion. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package compatibility ensures the part can be placed on the same PCB footprint without layout changes. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The temperature range confirms suitability for the target environment and industrial-grade reliability requirements. |

Frequently asked questions
What are the primary differences between the AD8009AR and AD8001AR-REEL?
The AD8009AR is a high-speed current feedback amplifier offering a 5 GHz gain bandwidth product and 5,500 V/µs slew rate, while the AD8001AR-REEL is a lower-power current feedback amplifier with a 1.2 GHz gain bandwidth product and 1,200 V/µs slew rate. The AD8009AR is supplied in a tube, whereas the AD8001AR-REEL is supplied on a 13-inch reel for automated assembly.
Are the AD8009AR and AD8001AR-REEL pin-compatible?
Yes. Both devices are offered in an 8-lead SOIC package with the same pinout, allowing them to share a common PCB footprint. However, pin compatibility does not guarantee electrical interchangeability in a given circuit.
Can the AD8009AR be used as a drop-in replacement for the AD8001AR-REEL?
Not without design verification. The AD8009AR draws significantly higher supply current and provides much greater bandwidth and slew rate than the AD8001AR-REEL, so feedback network values, stability, power dissipation, and supply decoupling must be re-evaluated against the AD8009 datasheet before substitution.
How do the supply current and power consumption of the two devices compare?
The AD8009AR typically draws about 16 mA per amplifier, while the AD8001AR-REEL typically draws about 5.5 mA per amplifier. The AD8001AR-REEL is therefore the lower-power option for power-sensitive designs.
What bandwidth and slew rate does each device provide?
The AD8009AR provides a 5 GHz gain bandwidth product and a 5,500 V/µs slew rate. The AD8001AR-REEL provides a 1.2 GHz gain bandwidth product and a 1,200 V/µs slew rate. The AD8009AR is intended for applications requiring the highest dynamic performance.
What is the difference between the AR and AR-REEL ordering designators?
The AR suffix denotes the 8-lead SOIC package. The -REEL suffix indicates that the AD8001AR-REEL is delivered on a 13-inch tape-and-reel carrier for high-volume automated placement, while the AD8009AR is supplied in standard tube packaging.
Which device is better suited for low-power or portable designs?
The AD8001AR-REEL is better suited for low-power designs because its typical supply current of about 5.5 mA per amplifier is substantially lower than the approximately 16 mA of the AD8009AR, reducing overall power consumption and thermal load.
Do both devices operate on the same supply voltage range?
Both are current feedback amplifiers designed for dual-supply operation, typically ±5 V, and each datasheet should be consulted for the exact specified operating range and absolute maximum ratings before use in a design.
