Replacement verdict
Compatible functional replacement candidate
The AD8009ARZ and AD8009AR are functionally equivalent current-feedback operational amplifiers from the same manufacturer family, sharing identical core electrical specifications and the same SOIC-8 package. The AD8009ARZ is the RoHS-compliant lead-free version of the AD8009AR, making it a suitable functional replacement candidate where lead-free compliance is required, with final validation recommended for supply-chain and solder-process compatibility.

Key electrical and mechanical differences between the two devices
| Parameter | AD8009ARZ | AD8009AR | Why it matters |
|---|---|---|---|
| Amplifier Type | Current Feedback | Current Feedback | Both are current-feedback op-amps, so the feedback topology and gain-setting behavior are interchangeable. |
| Number of Circuits | 1 | 1 | Single-channel configuration must match for direct board-level substitution. |
| -3dB Bandwidth | 1 GHz | 1 GHz | Bandwidth determines the maximum signal frequency the amplifier can handle in the target application. |
| Slew Rate | 5500 V/µs | 5500 V/µs | Slew rate limits large-signal transient response; identical values ensure equivalent pulse fidelity. |
| Supply Voltage Range | ±5 V to ±6 V (dual) | ±5 V to ±6 V (dual) | The supply range must be compatible with the existing power rails for the part to function correctly. |
| Input Offset Voltage | 2 mV (typ) | 2 mV (typ) | Offset voltage affects DC accuracy; matching values preserve the same error budget. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature range must cover the application environment for reliable operation. |
| Package / Mounting Type | 8-SOIC (RoHS-compliant, Pb-free) | 8-SOIC (leaded, non-RoHS) | Both are 8-SOIC surface-mount, but the RoHS/Pb-free difference affects compliance and solder process requirements. |
| RoHS Compliance | RoHS Compliant | Non-RoHS (contains lead) | RoHS status determines regulatory compliance and whether the part can be used in lead-free manufacturing lines. |

Frequently asked questions
What is the difference between AD8009ARZ and AD8009AR?
The AD8009ARZ is the RoHS-compliant, lead-free (Pb-free) version of the AD8009AR. Both are the same 1 GHz, 5,500 V/µs current feedback operational amplifier in an 8-lead SOIC package; the "Z" suffix in AD8009ARZ denotes the lead-free/RoHS-compliant package molding compound and termination finish per Analog Devices part numbering, while AD8009AR is the older leaded (non-RoHS) SOIC variant.
Are AD8009ARZ and AD8009AR electrically and functionally identical?
Yes. Both devices share the same die and datasheet specifications for the AD8009: 1 GHz -3 dB bandwidth (G = +1), 5,500 V/µs slew rate, 700 MHz large-signal bandwidth, and 15 mA typical supply current on ±5 V supplies. The only documented difference is the package finish/RoHS status, not the electrical performance.
Can AD8009ARZ be used as a drop-in replacement for AD8009AR?
Yes, in most cases. Both are 8-lead SOIC (R-8) packages with identical pinouts and identical electrical specifications, so AD8009ARZ can directly replace AD8009AR on an existing PCB. The substitution is typically made to achieve RoHS compliance; verify solder profile compatibility with the lead-free finish if the assembly process was qualified for the leaded part.
What package do AD8009ARZ and AD8009AR use?
Both parts are supplied in the 8-lead SOIC package (Analog Devices package code R-8), with the same body dimensions and pin configuration. The AD8009 is also offered in other packages (e.g., 8-lead LFCSP and 5-lead SOT-23), but the ARZ and AR suffixes specifically denote the 8-lead SOIC.
What are the key AC specifications shared by AD8009ARZ and AD8009AR?
Per the AD8009 datasheet, both variants provide 1 GHz -3 dB small-signal bandwidth at G = +1, 700 MHz large-signal bandwidth, 5,500 V/µs slew rate, and 0.02% differential gain / 0.01° differential phase error, making them suited to video and high-speed signal-chain applications.
Do AD8009ARZ and AD8009AR have the same supply voltage and power requirements?
Yes. Both operate from ±5 V nominal dual supplies (range typically ±2.5 V to ±6 V per the datasheet) and draw approximately 15 mA typical supply current. Power dissipation and thermal considerations are therefore identical between the two variants.
Is AD8009AR still recommended for new designs, or should AD8009ARZ be used?
For new designs, AD8009ARZ is the appropriate choice because it is the RoHS-compliant, lead-free variant and aligns with current environmental compliance requirements. AD8009AR is the legacy leaded version; designs requiring RoHS compliance should specify AD8009ARZ.
