Replacement verdict
Compatible functional replacement candidate
The AD8554ARZ and AD8554AR-REEL are functionally equivalent implementations of the same AD8554 quad zero-drift operational amplifier, differing only in packaging format. The AD8554ARZ is supplied in a 14-lead SOIC tube configuration, while the AD8554AR-REEL is the identical die and package delivered on tape-and-reel for automated assembly. Both share identical electrical specifications, pinout, and temperature range, making them interchangeable for design and qualification purposes; selection should be driven solely by the assembly process and inventory handling requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD8554ARZ | AD8554AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 4 | 4 | Determines how many independent op-amp channels are available in a single package for multi-channel signal conditioning. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Defines the compatible power rails; both parts support the same low-voltage single-supply and split-supply operation. |
| Input Offset Voltage (Max) | 5 µV | 5 µV | Ultra-low offset is critical for precision DC amplification and sensor interfaces where error budget is tight. |
| Input Bias Current (Typ) | 50 pA | 50 pA | Very low bias current minimizes errors in high-impedance sensor and photodiode front-ends. |
| Gain Bandwidth Product | 1.5 MHz | 1.5 MHz | Sets the achievable closed-loop bandwidth and slew performance for the amplifier stage. |
| Supply Current per Amplifier (Typ) | 850 µA | 850 µA | Affects power budget in battery-powered and portable precision instrumentation. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Confirms both parts are rated for industrial/extended temperature environments. |
| Package / Packaging | 14-Lead SOIC (tube) | 14-Lead SOIC (tape and reel) | Same package and die, but delivery format differs; tape-and-reel suits automated high-volume assembly while tube suits prototyping. |
| Ordering Part Number Status | Active / RoHS-compliant | Legacy reel variant (non-RoHS designation) | Affects compliance and lifecycle; the Z suffix denotes RoHS compliance, which matters for regulatory and procurement requirements. |

Frequently asked questions
What is the difference between AD8554ARZ and AD8554AR-REEL?
Both parts are the same AD8554 quad zero-drift operational amplifier in a 14-lead SOIC package. The difference is packaging format: AD8554ARZ is supplied in tube/tray quantities, while AD8554AR-REEL is supplied on tape and reel for automated assembly. The "Z" suffix in AD8554ARZ denotes RoHS-compliant lead-free construction, whereas AD8554AR-REEL is the reeled variant of the non-Z ordering code.
Are AD8554ARZ and AD8554AR-REEL electrically identical?
Yes. Both ordering codes refer to the same AD8554 silicon die with identical electrical specifications, including typical offset voltage of 1 µV, offset voltage drift of 0.005 µV/°C, and a gain bandwidth product of 1.5 MHz. The difference is limited to packaging and RoHS status, not device performance.
Do AD8554ARZ and AD8554AR-REEL differ in RoHS compliance?
Yes. The "Z" suffix in AD8554ARZ indicates RoHS-compliant, lead-free construction per Analog Devices ordering conventions. AD8554AR-REEL is the reeled version of the non-Z ordering code and should be verified against the manufacturer datasheet and packaging specification for its exact RoHS status before use in RoHS-restricted designs.
Can AD8554ARZ and AD8554AR-REEL be used interchangeably in a design?
Electrically and functionally yes, since both are the same AD8554 device in a 14-lead SOIC package. However, the choice between them depends on assembly method: AD8554AR-REEL is intended for automated pick-and-place reel-fed lines, while AD8554ARZ is supplied in tube/tray format. RoHS requirements must also be confirmed for the target design.
What package do AD8554ARZ and AD8554AR-REEL use?
Both are offered in the 14-lead SOIC (Small Outline Integrated Circuit) package, consistent with the "AR" package designator in the AD8554 ordering code. Pinout and package dimensions are identical between the two ordering codes.
What are the key specifications of the AD8554?
The AD8554 is a quad zero-drift operational amplifier featuring very low offset voltage (1 µV typical), low offset voltage drift (0.005 µV/°C typical), low input bias current, and rail-to-rail input and output operation. It operates from a single supply of 2.7 V to 5 V or dual supplies, with a gain bandwidth product of 1.5 MHz. These specifications apply equally to AD8554ARZ and AD8554AR-REEL.
Which ordering code should be selected for high-volume automated assembly?
AD8554AR-REEL is the appropriate choice for high-volume automated assembly because it is supplied on tape and reel, which is compatible with standard pick-and-place equipment. AD8554ARZ in tube/tray format is better suited to low-volume or prototype builds. Final selection should also account for the RoHS status required by the application.
