Replacement verdict
Compatible functional replacement candidate
The AD8552AR and AD8552AR-REEL7 are the same zero-drift, dual operational amplifier die offered under different packaging formats, with the REEL7 variant supplied on tape and reel for automated assembly. Both share identical electrical specifications, package type, and temperature range, making them functionally interchangeable; the only meaningful distinction is the shipping format, which should be confirmed against your production handling requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD8552AR | AD8552AR-REEL7 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Determines how many independent op-amp channels are available in a single package; must match for direct substitution. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Defines the operating supply window; identical range ensures the part works in the same circuit without redesign. |
| Input Offset Voltage (Max) | 5 µV | 5 µV | Ultra-low offset is the key precision characteristic of this amplifier; matching values preserve accuracy in sensor and instrumentation circuits. |
| Input Bias Current (Typ) | 10 pA | 10 pA | Very low bias current minimizes errors in high-impedance signal paths; identical values ensure equivalent performance. |
| Gain Bandwidth Product | 1.5 MHz | 1.5 MHz | Sets the achievable closed-loop bandwidth; matching GBW ensures the same frequency response in the application. |
| Supply Current per Amplifier (Typ) | 850 µA | 850 µA | Affects power budget and thermal behavior; identical quiescent current keeps power consumption unchanged. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Determines environmental suitability; matching range ensures the part can be used in the same temperature conditions. |
| Package / Mounting | 8-SOIC (Surface Mount) | 8-SOIC (Surface Mount) | Footprint and mounting style must match for board-level interchangeability. |
| Packaging / Delivery Form | Tube / Cut Tape | Tape & Reel (7-inch reel) | The only functional difference is the shipping format; reel packaging suits automated pick-and-place assembly while tube suits manual or low-volume use. |

Frequently asked questions
What is the difference between AD8552AR and AD8552AR-REEL7?
Both parts refer to the same AD8552 zero-drift operational amplifier in an 8-lead SOIC package. The AD8552AR is the base ordering code, while AD8552AR-REEL7 specifies tape-and-reel packaging (7-inch reel) for automated assembly. The electrical and package specifications are identical; only the packaging and ordering quantity differ.
Are AD8552AR and AD8552AR-REEL7 electrically identical?
Yes. Both ordering codes correspond to the same AD8552 die and 8-lead SOIC package. The "-REEL7" suffix denotes tape-and-reel packaging only and does not change electrical parameters such as offset voltage, gain bandwidth, or supply current.
What are the key specifications of the AD8552?
The AD8552 is a dual zero-drift operational amplifier featuring very low offset voltage (typically 1 µV, maximum 5 µV), low offset voltage drift (typically 0.005 µV/°C), rail-to-rail input and output, and a gain bandwidth product of 1.5 MHz. It operates from a 2.7 V to 5 V single supply (or ±1.35 V to ±2.5 V dual supply) with a typical supply current of 850 µA per amplifier.
Can AD8552AR and AD8552AR-REEL7 be used interchangeably in a design?
Yes. Since both ordering codes refer to the same device in the same 8-lead SOIC package, they are functionally and electrically interchangeable. The choice between them depends only on the assembly method: AD8552AR-REEL7 is supplied on 7-inch tape-and-reel for automated pick-and-place, while AD8552AR is supplied in standard tube or tray packaging.
What package does the AD8552AR use?
The AD8552AR is supplied in an 8-lead SOIC (Small Outline Integrated Circuit) package, designated "R" in the ordering code. The AD8552AR-REEL7 uses the same 8-lead SOIC package, with the "-REEL7" suffix indicating 7-inch tape-and-reel packaging.
What is the operating temperature range of the AD8552AR?
The AD8552AR is specified for operation over the extended industrial temperature range of −40 °C to +125 °C, consistent with the AD8552 datasheet specifications.
Why would a designer choose AD8552AR-REEL7 over AD8552AR?
AD8552AR-REEL7 is chosen when the production line uses automated pick-and-place assembly, as the 7-inch tape-and-reel format is compatible with standard SMT feeders. AD8552AR is typically selected for prototyping, low-volume runs, or manual assembly where tube or tray packaging is sufficient.
What are the typical applications of the AD8552?
The AD8552 is commonly used in precision sensor signal conditioning, temperature and pressure transducer interfaces, medical instrumentation, and low-level signal amplification where low offset voltage and low drift are critical. Its rail-to-rail input/output and single-supply operation make it suitable for portable and battery-powered precision systems.
