Replacement verdict
Compatible functional replacement candidate
The AD8552ARZ and AD8552AR-REEL7 are the same AD8552 zero-drift operational amplifier die in the same 8-lead SOIC package, differing only in packaging format (tube vs. tape-and-reel). They are functionally interchangeable for design, qualification, and PCB assembly purposes, with the reel variant suited to high-volume automated placement lines.

Key electrical and mechanical differences between the two devices
| Parameter | AD8552ARZ | AD8552AR-REEL7 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count matches for direct circuit substitution. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Identical operating supply range ensures the part works in the same power rails. |
| Input Offset Voltage (Max) | 5 µV | 5 µV | Zero-drift, ultra-low offset is the defining characteristic; matching values preserve precision performance. |
| Input Bias Current | 50 pA (typ) | 50 pA (typ) | Very low bias current is critical for high-impedance sensor interfaces; identical values mean equivalent behavior. |
| Gain Bandwidth Product | 1.5 MHz | 1.5 MHz | Same bandwidth supports the same signal frequency range in the application. |
| Package / Mounting | 8-SOIC (surface mount) | 8-SOIC (surface mount) | Identical package and footprint allow drop-in board replacement. |
| Packaging / Delivery Form | Tube | Tape & Reel (7-inch reel) | Delivery format differs; reel packaging suits automated high-volume assembly while tube suits prototyping or low-volume runs. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Same temperature rating ensures equivalent environmental robustness. |
| Supply Current per Amplifier | 850 µA (typ) | 850 µA (typ) | Identical quiescent current keeps power budget unchanged in low-power designs. |

Frequently asked questions
What is the difference between AD8552ARZ and AD8552AR-REEL7?
Both parts are the same AD8552 zero-drift, rail-to-rail operational amplifier in an 8-lead SOIC package. The difference is packaging format: AD8552ARZ is supplied in tube/tray quantities, while AD8552AR-REEL7 is supplied on a 7-inch tape-and-reel for automated assembly. The "Z" suffix in AD8552ARZ denotes RoHS-compliant lead-free construction; AD8552AR-REEL7 is the reeled variant of the same die and package.
Are AD8552ARZ and AD8552AR-REEL7 electrically and functionally identical?
Yes. Both are the AD8552 dual zero-drift amplifier with the same specified performance: low offset voltage (10 µV maximum), rail-to-rail input and output, single-supply operation from 2.7 V to 5 V, and low input bias current. The reeled and tube versions share the same datasheet specifications; only the shipping format differs.
Can AD8552AR-REEL7 be used as a drop-in replacement for AD8552ARZ in an existing design?
Yes, from an electrical and footprint standpoint they are interchangeable because both use the same 8-lead SOIC (R-8) package and pinout. The only practical consideration is assembly: AD8552AR-REEL7 is intended for pick-and-place reel-fed production, while AD8552ARZ is typically used for prototyping or low-volume hand assembly.
What package do AD8552ARZ and AD8552AR-REEL7 use?
Both devices are offered in the 8-lead SOIC package (Analog Devices R-8 suffix). The package is RoHS-compliant and lead-free, and the pinout is identical between the two orderable part numbers.
What supply voltage range do AD8552ARZ and AD8552AR-REEL7 support?
Both parts operate from a single supply of 2.7 V to 5 V, and can also be operated from dual supplies within that total range. They are specified for rail-to-rail input and output swing, making them suitable for low-voltage precision signal conditioning.
Which part number should be ordered for high-volume automated PCB assembly?
AD8552AR-REEL7 is the appropriate choice for high-volume automated assembly because it is supplied on 7-inch tape-and-reel, which is compatible with standard pick-and-place equipment. AD8552ARZ in tube form is better suited to prototyping, evaluation, and low-volume builds.
Do AD8552ARZ and AD8552AR-REEL7 differ in temperature range or qualification?
No. Both orderable part numbers are specified over the same industrial temperature range and share the same datasheet limits. The reeled and tube variants are not separately qualified; they are the same silicon and package, differing only in shipping media.
