Replacement verdict
Compatible functional replacement candidate
The AD8009AR and AD8001AR-REEL7 are both high-speed current-feedback operational amplifiers sharing the same SOIC-8 package and similar supply voltage ranges, making the AD8009AR a viable functional replacement candidate for the AD8001AR-REEL7 in many high-speed signal-chain applications. However, the AD8009AR offers substantially higher slew rate and bandwidth, so designers should validate stability, gain peaking, and power dissipation in the target circuit before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009AR | AD8001AR-REEL7 | Why it matters |
|---|---|---|---|
| -3 dB Bandwidth | 1 GHz (G = +2) | 800 MHz (G = +1) | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain; a higher bandwidth supports faster signal processing. |
| Slew Rate | 5500 V/µs | 1200 V/µs | Slew rate limits how fast the output can change; higher slew rate enables larger, faster signal swings without distortion. |
| Input Voltage Noise | 1.1 nV/√Hz | 2.0 nV/√Hz | Lower input voltage noise improves signal-to-noise ratio in low-level signal applications. |
| Supply Current per Amplifier | 16 mA | 5.5 mA | Supply current affects power consumption and thermal budget; lower current is preferable for power-sensitive designs. |
| Output Current | 175 mA | 70 mA | Output current capability determines the amplifier's ability to drive low-impedance loads such as cables or video terminations. |
| Input Offset Voltage (max) | 10 mV | 5 mV | Offset voltage introduces DC error at the output; lower offset improves DC accuracy in precision applications. |
| Supply Voltage Range | ±5 V to ±6 V (dual) | ±3 V to ±6 V (dual) | The supply range defines compatibility with system power rails; a wider range offers more flexibility in different designs. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package compatibility ensures the part can be placed on the same PCB footprint for drop-in substitution. |

Frequently asked questions
What are the primary differences between the AD8009AR and AD8001AR-REEL7?
The AD8009AR is a high-speed current-feedback amplifier optimized for very fast settling and high slew rate, while the AD8001AR-REEL7 is a lower-power current-feedback amplifier with lower quiescent current. The AD8009AR typically offers higher bandwidth and slew rate, whereas the AD8001AR-REEL7 is positioned for applications where power consumption is more critical. Both are supplied in 8-lead SOIC packages, but the AD8001AR-REEL7 is shipped in tape-and-reel format.
Are the AD8009AR and AD8001AR-REEL7 pin-compatible?
Yes. Both devices are offered in an 8-lead SOIC package with the same pinout (standard op-amp pin configuration for current-feedback amplifiers), so they are pin-compatible when both are in the SOIC-8 package. Designers should still verify the package drawing in the respective datasheets before layout substitution.
Can the AD8009AR be used as a drop-in replacement for the AD8001AR-REEL7?
Pin compatibility alone does not guarantee a drop-in replacement. The AD8009AR and AD8001AR-REEL7 differ in supply current, bandwidth, slew rate, and feedback resistor requirements for current-feedback operation. The feedback resistor value must be selected per each device's datasheet to maintain stability. A substitution should only be made after validating the closed-loop performance, stability, and power budget against the manufacturer datasheets.
How do the supply current and power consumption of the two devices compare?
The AD8001AR-REEL7 is specified with a lower typical quiescent supply current than the AD8009AR, making it preferable for power-sensitive designs. The AD8009AR draws more supply current in exchange for higher speed. Exact quiescent current values should be taken from the respective Analog Devices datasheets, as they are specified under defined test conditions.
What are the bandwidth and slew rate characteristics of each device?
The AD8009AR is specified with a higher small-signal bandwidth and higher slew rate than the AD8001AR-REEL7, reflecting its positioning as a very high-speed current-feedback amplifier. The AD8001AR-REEL7 offers lower bandwidth and slew rate but with reduced power consumption. Both are current-feedback amplifiers, so their bandwidth depends on the feedback resistor value; refer to the Analog Devices datasheets for the specified test conditions and guaranteed limits.
What package and packaging options are available for these parts?
Both the AD8009AR and AD8001AR-REEL7 are offered in an 8-lead SOIC package. The AD8009AR designation refers to the SOIC-8 package in tube form, while the AD8001AR-REEL7 suffix indicates tape-and-reel packaging for automated assembly. Package and ordering details should be confirmed against the Analog Devices ordering guide.
Which device is better suited for low-power portable applications?
The AD8001AR-REEL7 is generally better suited for low-power applications because it is specified with lower quiescent supply current than the AD8009AR. The AD8009AR is intended for applications prioritizing maximum speed and slew rate over power consumption. Final selection should be based on the supply current and bandwidth requirements verified in the respective datasheets.
Do both devices require an external feedback resistor for stable operation?
Yes. Both the AD8009AR and AD8001AR-REEL7 are current-feedback amplifiers and require an external feedback resistor for stable closed-loop operation. The recommended feedback resistor value differs between the two devices and must be selected according to each datasheet; using a value optimized for one device with the other can degrade stability or bandwidth.
