Key electrical and mechanical differences between the two devices
| Parameter | AD8552AR | AD8554ARZ-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 multi-channel designs. |
| Input Offset Voltage (max) | 5 µV | 5 µV | Ultra-low offset is critical for precision DC and low-frequency signal conditioning; matching values preserve accuracy when substituting. |
| Input Offset Voltage Drift (max) | 0.05 µV/°C | 0.05 µV/°C | Low drift maintains precision over temperature; identical drift ensures comparable performance across the operating range. |
| Input Bias Current (typ) | 50 pA | 50 pA | Very low bias current suits high-impedance sensor interfaces; matching values preserve input loading behavior. |
| Gain Bandwidth Product | 1.5 MHz | 1.5 MHz | GBW sets the achievable closed-loop bandwidth; identical GBW means equivalent AC response for the same gain configuration. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply range ensures the part works in the same single-supply or low-voltage systems without redesign. |
| Supply Current per Amplifier (typ) | 0.85 mA | 0.85 mA | Quiescent current affects power budget; equal per-amplifier current keeps power scaling predictable with channel count. |
| Input Voltage Noise Density (typ) | 32 nV/√Hz | 32 nV/√Hz | Noise density governs the noise floor of the signal chain; matching values preserve SNR in low-level signal applications. |
| Package Type | 8-lead SOIC | 14-lead SOIC | Different package footprints and pin counts require PCB layout changes; they are not drop-in replacements. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Identical temperature ratings ensure both parts meet the same environmental requirements for industrial and automotive use. |

Frequently asked questions
What are the key differences between the AD8552AR and AD8554ARZ-REEL?
The AD8552AR is a dual-channel zero-drift operational amplifier in an 8-lead SOIC package, while the AD8554ARZ-REEL is a quad-channel zero-drift operational amplifier in a 14-lead SOIC package supplied in tape-and-reel format. Both share the same core amplifier architecture and similar per-channel specifications, but differ in channel count, package size, and packaging format.
Are the AD8552AR and AD8554ARZ-REEL electrically identical on a per-channel basis?
Yes. Both devices are members of the AD855x zero-drift amplifier family and share the same per-channel specifications, including very low offset voltage, low offset voltage drift, and rail-to-rail input and output operation. The primary differences are channel count and package, not per-channel electrical performance.
Can the AD8552AR be used as a drop-in replacement for the AD8554ARZ-REEL?
No. The AD8552AR is a dual amplifier in an 8-lead SOIC package, whereas the AD8554ARZ-REEL is a quad amplifier in a 14-lead SOIC package. The pin counts, pin functions, and PCB land patterns differ, so a direct drop-in substitution is not possible without a board redesign.
What supply voltage range do the AD8552AR and AD8554ARZ-REEL support?
Both devices operate from a single supply of 2.7 V to 5 V, or from dual supplies of ±1.35 V to ±2.5 V, as specified in the Analog Devices AD855x datasheet. Designs should be validated against the manufacturer datasheet for the exact operating conditions.
What packaging format does the AD8554ARZ-REEL use?
The AD8554ARZ-REEL is supplied in a 14-lead SOIC package in tape-and-reel format, which is intended for automated high-volume assembly. The AD8552AR is supplied in an 8-lead SOIC package; reel availability should be confirmed against the specific ordering part number.
Do both parts share the same zero-drift amplifier technology?
Yes. Both the AD8552AR and AD8554ARZ-REEL are zero-drift operational amplifiers from the Analog Devices AD855x family, using auto-zeroing/chopper-stabilized architecture to achieve very low offset voltage and offset voltage drift. Consult the official datasheet for the exact guaranteed limits.
Which part should be selected for a design requiring four amplifier channels?
The AD8554ARZ-REEL should be selected, as it is the quad-channel device in the family. The AD8552AR provides only two channels and would require two packages to implement four channels, increasing board area and component count.
Are the AD8552AR and AD8554ARZ-REEL RoHS compliant?
The AD8554ARZ-REEL carries the "Z" suffix in its ordering code, which denotes a RoHS-compliant package per Analog Devices ordering conventions. RoHS status for the AD8552AR depends on the specific ordering part number; verify compliance on the manufacturer datasheet or distributor listing before use.
