Replacement verdict
Compatible functional replacement candidate
The AD8552AR and AD8554AR-REEL share the same zero-drift amplifier core, supply range, and package family, making them functionally related but not pin-for-pin interchangeable due to differing channel counts. The AD8552AR is a dual-channel device while the AD8554AR-REEL is a quad-channel device, so substitution requires validation of channel count, board footprint, and pinout before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AD8552AR | AD8554AR-REEL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 (dual) | 4 (quad) | Channel count determines how many independent signal paths can be processed; a dual cannot directly replace a quad in a four-channel circuit. |
| Input Offset Voltage (max) | 5 µV | 5 µV | Ultra-low offset is the defining feature of these zero-drift amplifiers; matching offset ensures comparable DC accuracy in precision signal chains. |
| Input Offset Voltage Drift (max) | 0.05 µV/°C | 0.05 µV/°C | Low drift maintains precision over temperature, critical for sensor interfaces and instrumentation where offset stability is required. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply range allows both parts to operate from the same single-supply rails, enabling drop-in use in the same power domain. |
| Gain Bandwidth Product | 1.5 MHz | 1.5 MHz | Identical bandwidth ensures the same closed-loop frequency response and settling behavior for signal conditioning stages. |
| Input Bias Current (typ) | 50 pA | 50 pA | Very low bias current minimizes errors in high-impedance sources such as photodiodes and precision resistor networks. |
| Supply Current per Amplifier (typ) | 850 µA | 850 µA | Per-amplifier quiescent current affects total power budget; matching values keeps power consumption predictable when channel count changes. |
| Package | 8-lead SOIC | 14-lead SOIC | Different package footprints and pin counts prevent direct board-level substitution without layout changes. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Identical temperature ratings ensure both parts meet the same environmental and reliability requirements in industrial applications. |

Frequently asked questions
What is the primary difference between the AD8552AR and AD8554AR-REEL?
The AD8552AR is a dual-channel zero-drift operational amplifier, while the AD8554AR-REEL is a quad-channel zero-drift operational amplifier. Both are from the same Analog Devices AD855x family and share similar per-channel specifications, but differ in channel count and package pinout.
Are the AD8552AR and AD8554AR-REEL pin-compatible?
No. The AD8552AR is a dual op-amp in an 8-lead SOIC package, while the AD8554AR-REEL is a quad op-amp in a 14-lead SOIC package. They have different pin counts and pinouts, so they are not directly interchangeable on the same PCB footprint.
Do the AD8552AR and AD8554AR-REEL share the same supply voltage range?
Yes. Both devices operate from a single supply of 2.7 V to 5 V or a dual supply of ±1.35 V to ±2.5 V, as specified in the Analog Devices AD855x datasheet.
What is the input offset voltage specification for these amplifiers?
Both the AD8552AR and AD8554AR-REEL feature very low input offset voltage, typically 1 µV maximum, with offset drift of 0.005 µV/°C typical, per the Analog Devices datasheet for the AD855x family.
What does the "-REEL" suffix indicate on the AD8554AR-REEL?
The "-REEL" suffix indicates that the AD8554AR is supplied in tape-and-reel packaging, which is intended for automated high-volume PCB assembly. The AD8552AR is typically supplied in tube or standard packaging unless a reel variant is explicitly ordered.
Can the AD8552AR be used as a drop-in replacement for the AD8554AR-REEL in an existing design?
No. Because the AD8552AR is a dual op-amp in an 8-lead package and the AD8554AR-REEL is a quad op-amp in a 14-lead package, a direct drop-in replacement is not possible. A redesign of the PCB layout and pinout would be required.
Do both devices offer rail-to-rail input and output capability?
Yes. Both the AD8552AR and AD8554AR-REEL feature rail-to-rail input and output swing, as stated in the Analog Devices AD855x datasheet, making them suitable for low-voltage single-supply signal conditioning.
What is the typical gain bandwidth product for these amplifiers?
Both the AD8552AR and AD8554AR-REEL have a gain bandwidth product of 1.5 MHz typical, according to the Analog Devices AD855x datasheet.
