Replacement verdict
Compatible functional replacement candidate
The AD8534ARZ and AD8534AR-REEL are functionally equivalent, sharing the same quad operational amplifier die, package type, and electrical specifications; the only distinction is the packaging format, with the REEL variant supplied on tape and reel for automated assembly. Either part number can serve as a direct substitute for the other in the same application.

Key electrical and mechanical differences between the two devices
| Parameter | AD8534ARZ | AD8534AR-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 6 V | 2.7 V to 6 V | Defines the operating voltage window; both parts must match to ensure compatibility with the system power rail. |
| Gain Bandwidth Product | 3 MHz | 3 MHz | Sets the maximum frequency at which the amplifier can provide useful gain, affecting signal bandwidth capability. |
| Input Offset Voltage (max) | 25 mV | 25 mV | Limits DC accuracy; a lower offset improves precision in sensor and instrumentation front-ends. |
| Output Current per Channel | 250 mA | 250 mA | Determines drive capability for loads such as headphones or small actuators; high output current enables direct load driving. |
| Package / Mounting | 14-Lead SOIC (surface mount) | 14-Lead SOIC (surface mount) | Must match the PCB footprint and assembly process for drop-in substitutability. |
| Packaging / Delivery Form | Tube | Tape & Reel | Affects manufacturing handling: tape-and-reel suits automated pick-and-place lines, while tubes suit low-volume or manual assembly. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device meets performance specifications across the intended application environment. |
| Quiescent Supply Current (per amplifier) | 1.2 mA | 1.2 mA | Impacts power budget in battery-powered and portable designs; identical values confirm equivalent power consumption. |

Frequently asked questions
What is the difference between AD8534ARZ and AD8534AR-REEL?
Both parts are the same AD8534 quad operational amplifier die in an 8-lead SOIC package (R-8 suffix). The AD8534ARZ is supplied in tube/rail packaging and carries the RoHS-compliant "Z" designation. The AD8534AR-REEL is the same device supplied on tape-and-reel for automated assembly; the non-Z suffix indicates the earlier non-RoHS lead-frame finish. Electrical performance is identical; the differences are packaging format and RoHS compliance status.
Are the AD8534ARZ and AD8534AR-REEL electrically identical?
Yes. Both are the AD8534 quad rail-to-rail input/output operational amplifier with the same specified parameters, including a 3 MHz gain-bandwidth product, 5 V/µs slew rate, and operation from a single 2.7 V to 6 V supply (or ±1.35 V to ±3 V dual supply). The datasheet specifications apply equally to both orderable part numbers.
Can AD8534AR-REEL be used as a drop-in replacement for AD8534ARZ?
Electrically and functionally yes, since both are the same AD8534 die in the same 8-lead SOIC footprint. However, the AD8534AR-REEL is the non-RoHS version, so it should not be substituted where RoHS compliance is a requirement. Confirm the assembly process and compliance requirements before substituting.
What package do the AD8534ARZ and AD8534AR-REEL use?
Both parts are offered in the 8-lead SOIC package, identified by the "R-8" package designator in the ordering code. The package outline and pinout are identical, so PCB land patterns are interchangeable between the two orderable part numbers.
Why choose the REEL version over the tube version?
The AD8534AR-REEL tape-and-reel format is intended for high-volume automated pick-and-place assembly, which is more efficient than handling tube/rail packaging. The AD8534ARZ tube format is typically used for prototyping, low-volume runs, or manual assembly. Selection depends on production volume and handling equipment rather than electrical differences.
What are the key specifications of the AD8534?
The AD8534 is a quad rail-to-rail input/output operational amplifier with a 3 MHz gain-bandwidth product, 5 V/µs slew rate, and low input bias current. It operates from a single 2.7 V to 6 V supply or a dual ±1.35 V to ±3 V supply, making it suitable for low-voltage, single-supply signal conditioning applications.
Does the "Z" suffix affect the technical performance of AD8534ARZ?
No. The "Z" suffix in the AD8534ARZ ordering code denotes RoHS compliance (lead-free finish), not a change in electrical specifications. The AD8534ARZ and AD8534AR-REEL share the same datasheet performance characteristics; only the package finish and shipping format differ.
