Replacement verdict
Compatible functional replacement candidate
The AD8009ARZ and AD8002ARZ-RL are both high-speed current-feedback operational amplifiers from Analog Devices in the same 8-lead SOIC package, sharing a common supply range and similar bandwidth class, so the AD8002ARZ-RL can serve as a functional replacement candidate for the AD8009ARZ in many designs. However, the two parts differ in channel count and key AC specifications, so the replacement must be validated against the target application's gain, slew-rate, and thermal requirements before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009ARZ | AD8002ARZ-RL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 1 | 2 | Determines how many independent signal channels are available in a single package; a dual amplifier can replace two singles but not vice versa. |
| -3 dB Bandwidth | 1 GHz | 600 MHz | Sets the maximum usable signal frequency; the AD8009 supports higher-speed signals than the AD8002. |
| Slew Rate | 5500 V/µs | 1200 V/µs | Governs large-signal transient response; a higher slew rate enables faster edge handling and lower distortion at high frequencies. |
| Supply Voltage Range | ±5 V to ±6 V (10 V to 12 V) | ±3 V to ±6 V (6 V to 12 V) | Defines the allowable power supply; the AD8002 can operate at lower supply voltages where the AD8009 cannot. |
| Supply Current per Amplifier | 16 mA typ | 7 mA typ | Affects power budget and thermal design; the AD8002 draws significantly less current per amplifier. |
| Input Voltage Noise | 1.1 nV/√Hz | 2 nV/√Hz | Determines noise floor in low-level signal applications; lower input noise improves signal-to-noise ratio. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Footprint and pinout compatibility affect board layout; both share the same package outline but differ in pin function due to single vs dual configuration. |
| Output Current | 175 mA | 80 mA | Sets drive capability for loads such as cables or ADCs; higher output current supports heavier loads. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms both parts are rated for the same industrial temperature environment. |

Frequently asked questions
What are the primary differences between the AD8009ARZ and AD8002ARZ-RL?
The AD8009ARZ is a single, high-speed current feedback amplifier optimized for very high slew rate and low distortion, while the AD8002ARZ-RL is a dual current feedback amplifier supplied in a tape-and-reel packaging format. The AD8009ARZ is specified for a 5 V supply with a 1 GHz gain bandwidth product and 5500 V/µs slew rate, whereas the AD8002ARZ-RL offers two amplifiers per package with a 600 MHz gain bandwidth product and 1200 V/µs slew rate per amplifier.
Are the AD8009ARZ and AD8002ARZ-RL pin-compatible?
No. The AD8009ARZ is a single amplifier in an 8-lead SOIC package, while the AD8002ARZ-RL is a dual amplifier in an 8-lead SOIC package. Although both use the same 8-lead SOIC footprint, the pin functions differ because the AD8002ARZ-RL contains two independent amplifiers, so the pinout is not interchangeable.
Can the AD8009ARZ be used as a direct replacement for the AD8002ARZ-RL in an existing design?
No. The AD8009ARZ is a single amplifier and the AD8002ARZ-RL is a dual amplifier. A direct replacement is not possible without redesigning the circuit to account for the different channel count, pinout, and per-amplifier performance specifications.
What are the gain bandwidth and slew rate specifications for each device?
The AD8009ARZ has a gain bandwidth product of 1 GHz and a slew rate of 5500 V/µs. The AD8002ARZ-RL has a gain bandwidth product of 600 MHz per amplifier and a slew rate of 1200 V/µs per amplifier. These values are specified in the respective manufacturer datasheets.
What supply voltage ranges do the AD8009ARZ and AD8002ARZ-RL support?
Both devices are specified for operation on ±5 V dual supplies or a single 5 V to 10 V supply, depending on the configuration. The AD8009ARZ datasheet specifies operation from ±5 V supplies, and the AD8002ARZ-RL datasheet specifies operation from ±5 V supplies as well. Designers should confirm the exact supply range in the manufacturer datasheet for the intended operating conditions.
What package and packaging options are available for these parts?
The AD8009ARZ is supplied in an 8-lead SOIC package in tube or tray format. The AD8002ARZ-RL is supplied in an 8-lead SOIC package in tape-and-reel format, as indicated by the -RL suffix. Both are surface-mount SOIC packages, but the packaging format differs for production handling.
Which device is better suited for multi-channel signal processing?
The AD8002ARZ-RL is better suited for multi-channel signal processing because it integrates two current feedback amplifiers in a single 8-lead SOIC package, reducing board space and component count. The AD8009ARZ contains only one amplifier and would require two devices for a two-channel implementation.
Do both devices share the same operating temperature range?
Both the AD8009ARZ and AD8002ARZ-RL are specified for the industrial temperature range of −40°C to +85°C, as stated in their respective manufacturer datasheets. Designers should verify the exact temperature grade in the datasheet for the specific orderable part number.
