Replacement verdict
Compatible functional replacement candidate
The AD8009ARZ and AD8002AR-REEL are both high-speed current-feedback operational amplifiers from Analog Devices in the same SOIC-8 package, sharing a comparable supply voltage range and similar bandwidth class. However, they differ in channel count and key AC specifications, so the AD8002AR-REEL can serve as a functional candidate only after validating the channel configuration and dynamic performance requirements of the target design.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009ARZ | AD8002AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | A single vs. dual amplifier changes channel count and board layout; a dual can replace two singles but not vice versa. |
| -3 dB Bandwidth | 1 GHz | 600 MHz | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain roll-off. |
| Slew Rate | 5500 V/µs | 1200 V/µs | Slew rate limits how fast the output can respond to large signal steps; critical for high-speed pulse and video applications. |
| Supply Voltage Range | ±5 V to ±6 V (10 V to 12 V) | ±5 V to ±6 V (10 V to 12 V) | Operating supply range must match the system rails; both support similar bipolar supplies. |
| Input Offset Voltage (max) | 10 mV | 5 mV | Offset voltage affects DC accuracy; lower offset reduces output error in precision signal chains. |
| Quiescent Supply Current per Amplifier | 16 mA | 7 mA | Quiescent current impacts power budget and thermal design, especially in multi-channel or portable systems. |
| Output Current | 175 mA | 80 mA | Output drive capability determines ability to drive low-impedance loads such as cables or ADCs. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package footprint must match the PCB land pattern for drop-in compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment for reliable operation. |

Frequently asked questions
What are the primary differences between the AD8009ARZ and AD8002AR-REEL?
The AD8009ARZ 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 AD8009ARZ and AD8002AR-REEL pin-compatible?
No. Although both devices use an 8-lead SOIC package, the AD8009ARZ is a single amplifier with a different pin function assignment than the AD8002AR-REEL, which is a dual amplifier. The pinouts are not interchangeable, and the PCB layout must be designed for the specific device.
Can the AD8009ARZ be used as a drop-in replacement for the AD8002AR-REEL?
No. The AD8009ARZ is a single amplifier and the AD8002AR-REEL is a dual amplifier; they differ in channel count, pinout, and package pin functions. A direct drop-in replacement is not possible without redesigning the circuit and PCB layout.
What are the typical applications for the AD8009ARZ?
The AD8009ARZ is typically used in high-speed signal processing applications such as video amplification, ADC drivers, pulse amplifiers, and other circuits requiring high slew rate and wide bandwidth in a single-amplifier configuration.
What are the typical applications for the AD8002AR-REEL?
The AD8002AR-REEL is typically used in dual-channel high-speed applications such as differential signal chains, dual video amplifiers, and multi-channel ADC driving, where two matched current feedback amplifiers in a single package are advantageous.
Does the AD8002AR-REEL being supplied on tape and reel affect its electrical performance?
No. Tape and reel is a packaging format intended for automated assembly equipment. The electrical performance of the AD8002AR-REEL is determined by the device itself and is not affected by the tape and reel packaging.
Which device should be selected for a design requiring two amplifier channels?
The AD8002AR-REEL should be selected when two current feedback amplifiers are required, as it integrates two channels in a single 8-lead SOIC package. The AD8009ARZ provides only a single amplifier channel and would require two devices to achieve the same channel count.
