Replacement verdict
Compatible functional replacement candidate
The AD8552ARZ and AD8552AR-REEL are functionally equivalent, sharing the same zero-drift dual operational amplifier die, package, and specified electrical performance. The only meaningful distinction is the delivery format: the AD8552ARZ is supplied in tube packaging, while the AD8552AR-REEL is supplied on tape and reel for automated assembly. Either part can serve as a direct functional substitute for the other, with the selection driven by the production handling method rather than by any electrical or mechanical difference.

Frequently asked questions
What is the difference between AD8552ARZ and AD8552AR-REEL?
Both parts are the same AD8552 zero-drift, rail-to-rail operational amplifier die in an 8-lead SOIC package. The difference is packaging format: AD8552ARZ is supplied in tube/tray quantities, while AD8552AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix in AD8552ARZ denotes RoHS-compliant lead finish, whereas AD8552AR-REEL is the non-Z (non-RoHS) reel variant.
Are AD8552ARZ and AD8552AR-REEL electrically identical?
Yes. Both are the AD8552 dual zero-drift amplifier with the same specified electrical performance, including low offset voltage, rail-to-rail input and output, and single-supply operation from 2.7 V to 5 V. The datasheet parameters apply equally to both orderable part numbers.
Can AD8552ARZ and AD8552AR-REEL be used interchangeably in a design?
Electrically they are interchangeable, but the RoHS status differs. AD8552ARZ is RoHS-compliant, while AD8552AR-REEL is the non-RoHS reel variant. Substitution should be validated against the target design's compliance requirements and the manufacturer's orderable part number documentation.
What package do AD8552ARZ and AD8552AR-REEL use?
Both are offered in the 8-lead SOIC (Small Outline Integrated Circuit) package, designated by the "R" in the part number. The package outline and pin configuration are identical between the two orderable variants.
Why would a designer choose AD8552AR-REEL over AD8552ARZ?
AD8552AR-REEL is supplied on tape-and-reel, which suits high-volume automated pick-and-place assembly lines. AD8552ARZ in tube/tray form is typically used for prototyping, low-volume runs, or manual assembly. The choice is driven by production format and RoHS compliance needs, not by electrical differences.
What are the key specifications of the AD8552 amplifier?
The AD8552 is a dual zero-drift operational amplifier featuring very low offset voltage and offset drift, rail-to-rail input and output swing, and operation from a single supply of 2.7 V to 5 V. It is intended for precision, low-frequency signal conditioning where DC accuracy and low drift are critical. Refer to the official datasheet for exact guaranteed limits.
Does the "Z" suffix affect the electrical performance of AD8552ARZ?
No. The "Z" suffix designates RoHS compliance (lead-free finish) and does not change the amplifier's electrical specifications. AD8552ARZ and the non-Z AD8552AR-REEL share the same datasheet electrical characteristics.
