Replacement verdict
Compatible functional replacement candidate
The AD8529ARZ and AD8529AR-REEL are functionally equivalent dual operational amplifiers from the same manufacturer, differing only in packaging format. The AD8529ARZ is supplied in a tube, while the AD8529AR-REEL is supplied on tape and reel for automated assembly. Both share identical die, electrical specifications, and package type, making them interchangeable for design and functional purposes; selection should be based on production handling requirements rather than electrical performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD8529ARZ | AD8529AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | General Purpose, Dual | General Purpose, Dual | Confirms both parts are dual general-purpose op-amps, ensuring functional equivalence in circuit topology. |
| Number of Channels | 2 | 2 | Channel count must match for pin-compatible substitution in dual-amplifier designs. |
| Supply Voltage Range | 2.7 V to 12 V | 2.7 V to 12 V | Identical operating supply range ensures the part works in the same power environment. |
| Gain Bandwidth Product | 8 MHz | 8 MHz | GBW determines AC performance and stability; matching values preserve frequency response. |
| Input Offset Voltage (max) | 1 mV | 1 mV | Offset voltage affects DC accuracy; identical limits ensure equivalent precision performance. |
| Input Bias Current | 0.5 µA | 0.5 µA | Bias current impacts high-impedance input accuracy; matching values preserve error budgets. |
| Slew Rate | 2.5 V/µs | 2.5 V/µs | Slew rate limits large-signal response; identical values ensure the same dynamic behavior. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Same package and mounting type guarantee PCB footprint and assembly compatibility. |
| Packaging / Delivery Form | Tube | Tape & Reel | Delivery form affects manufacturing handling; reel suits automated pick-and-place while tube suits manual or low-volume assembly. |

Frequently asked questions
What is the difference between AD8529ARZ and AD8529AR-REEL?
Both parts are the same AD8529 dual operational amplifier die in an 8-lead SOIC package; the difference is packaging format. AD8529ARZ is supplied in tube/tray quantities, while AD8529AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix in AD8529ARZ denotes RoHS-compliant lead-free construction per Analog Devices nomenclature.
Are AD8529ARZ and AD8529AR-REEL electrically and functionally identical?
Yes. Both are the AD8529, a dual, low-noise, rail-to-rail output operational amplifier. The electrical specifications, pinout, and 8-lead SOIC (R-8) package are the same; only the shipping container differs.
Can AD8529AR-REEL be used as a drop-in replacement for AD8529ARZ in an existing design?
Yes, from an electrical and footprint standpoint the devices are interchangeable because they share the same die and 8-lead SOIC package. The choice between them is driven by assembly method (reel-fed pick-and-place vs. tube/tray handling), not by performance.
What package do AD8529ARZ and AD8529AR-REEL use?
Both are offered in the 8-lead SOIC package (Analog Devices package code R-8). The "AR" suffix in both part numbers designates the SOIC package grade.
Why would a design choose AD8529AR-REEL over AD8529ARZ?
AD8529AR-REEL is supplied on tape-and-reel, which is the standard format for high-volume automated surface-mount pick-and-place assembly. AD8529ARZ in tube/tray form is typically used for prototyping, low-volume runs, or manual assembly.
Do AD8529ARZ and AD8529AR-REEL differ in RoHS/lead-free status?
The "Z" in AD8529ARZ explicitly indicates RoHS-compliant, lead-free construction per Analog Devices part-numbering convention. Designers should confirm the RoHS status of the specific AD8529AR-REEL ordering code against the manufacturer datasheet or product page before assuming equivalence, since the reel variant's suffix does not carry the "Z" designator.
What are the key specifications shared by AD8529ARZ and AD8529AR-REEL?
Both are dual rail-to-rail output op amps with low noise and low input bias current, operating from a single supply (approximately 2.7 V to 12 V) or split supplies. For exact limits on noise density, bandwidth, offset voltage, and supply current, consult the official Analog Devices AD8529 datasheet, as these parameters are identical for both ordering variants.
