Replacement verdict
Compatible functional replacement candidate
The AD8022ARZ and AD8022AR-REEL are functionally identical dual high-speed voltage-feedback operational amplifiers from Analog Devices, differing only in packaging format. The AD8022ARZ is supplied in an anti-static tube, while the AD8022AR-REEL is supplied on tape-and-reel for automated assembly. Both share the same die, electrical specifications, and 8-lead SOIC footprint, making them interchangeable for design and qualification purposes; selection should be driven solely by the production handling method required.

Key electrical and mechanical differences between the two devices
| Parameter | AD8022ARZ | AD8022AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op-amps, so the feedback topology and compensation behavior are the same. |
| Number of Channels | 2 | 2 | Dual-channel configuration determines board layout and pin count compatibility. |
| Gain Bandwidth Product | 100 MHz | 100 MHz | GBW sets the achievable closed-loop bandwidth and is critical for signal-chain performance. |
| Slew Rate | 100 V/µs | 100 V/µs | Slew rate limits large-signal response and distortion at high frequencies. |
| Input Offset Voltage | 1.5 mV (max) | 1.5 mV (max) | Offset voltage affects DC accuracy and error budget in precision applications. |
| Supply Voltage Range | ±2.5 V to ±12 V | ±2.5 V to ±12 V | Supply range determines compatibility with the system power rails. |
| Package / Mounting | 8-SOIC (Surface Mount) | 8-SOIC (Surface Mount) | Package and mounting style must match the PCB footprint for drop-in substitution. |
| Packaging / Delivery Form | Tube | Tape & Reel | Delivery form affects assembly line handling; tape and reel suits automated pick-and-place, tube suits manual or low-volume assembly. |

Frequently asked questions
What is the difference between AD8022ARZ and AD8022AR-REEL?
Both are the same AD8022 dual high-speed operational amplifier die in an 8-lead SOIC package. The difference is packaging format: AD8022ARZ is supplied in tube/rail form, while AD8022AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix in AD8022ARZ denotes RoHS-compliant lead-free construction per Analog Devices nomenclature.
Are AD8022ARZ and AD8022AR-REEL electrically and functionally identical?
Yes. Both variants share the same datasheet specifications for the AD8022, including dual voltage-feedback architecture, low noise, and high output drive. Package, pinout, and electrical performance are identical; only the shipping media differ.
Can AD8022ARZ and AD8022AR-REEL be used interchangeably in the same PCB design?
Yes, provided the board is designed for the 8-lead SOIC (R-8) package. Both variants use the same package and pinout, so footprint and land pattern are identical. The choice between them is driven by assembly method (manual/tube vs. automated pick-and-place reel).
Which variant should be selected for automated SMT production lines?
AD8022AR-REEL is the appropriate choice for automated surface-mount assembly because it is supplied on tape-and-reel, which is compatible with standard pick-and-place feeders. AD8022ARZ in tube/rail form is typically used for prototyping, low-volume, or manual assembly.
Does the "Z" suffix on AD8022ARZ indicate a different silicon revision than AD8022AR-REEL?
No. Per Analog Devices part-numbering convention, the "Z" suffix indicates RoHS-compliant, lead-free packaging, not a different die or silicon revision. Both variants are based on the same AD8022 operational amplifier.
What package do AD8022ARZ and AD8022AR-REEL use?
Both are offered in the 8-lead SOIC package (Analog Devices package code R-8). Designers should confirm the exact package drawing and land pattern from the official AD8022 datasheet before layout.
Are AD8022ARZ and AD8022AR-REEL RoHS compliant?
AD8022ARZ carries the "Z" RoHS-compliant designation per Analog Devices part numbering. For AD8022AR-REEL, RoHS status should be confirmed against the specific ordering code and the manufacturer's product page or datasheet, since compliance is tied to the exact orderable part number.
