Replacement verdict
Compatible functional replacement candidate
The AD826AR and AD826AR-REEL are functionally identical dual high-speed operational amplifiers; the only distinction is packaging format, with the REEL variant supplied on tape and reel for automated assembly. Both share the same die, electrical specifications, and SOIC-8 footprint, making them fully interchangeable in design and function, with the choice driven solely by production handling requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD826AR | AD826AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback, Dual | Voltage Feedback, Dual | Confirms both parts are the same dual voltage-feedback op-amp architecture, ensuring functional equivalence. |
| Number of Channels | 2 | 2 | Channel count must match for direct board-level substitution in dual-amplifier circuits. |
| Gain Bandwidth Product | 50 MHz | 50 MHz | Determines the maximum frequency range over which the amplifier provides usable gain; identical values ensure equivalent AC performance. |
| Slew Rate | 350 V/µs | 350 V/µs | Affects large-signal transient response and distortion; matching slew rate preserves dynamic behavior. |
| Input Offset Voltage (Max) | 0.5 mV | 0.5 mV | DC accuracy depends on offset voltage; identical limits ensure the same precision in signal conditioning. |
| Supply Voltage Range | ±5 V to ±15 V | ±5 V to ±15 V | Confirms both parts operate over the same supply rails, allowing use in the same power environment. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Package and mounting style must match for physical drop-in compatibility on the PCB. |
| Packaging / Delivery Form | Tube / Cut Tape | Tape & 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 AD826AR and AD826AR-REEL?
The AD826AR and AD826AR-REEL are the same AD826 dual high-speed operational amplifier die in the same 8-lead SOIC (R-8) package. The only difference is packaging format: AD826AR is supplied in tubes, while AD826AR-REEL is supplied on tape and reel for automated assembly. Electrical and thermal specifications are identical.
Are AD826AR and AD826AR-REEL electrically and functionally interchangeable?
Yes. Both order codes refer to the same AD826AR grade device in an 8-lead SOIC package, so they are electrically and functionally interchangeable. The choice between them is driven by the board assembly method (tube-fed vs. tape-and-reel pick-and-place), not by performance.
What are the key specifications of the AD826?
The AD826 is a dual, low-power, high-speed voltage-feedback operational amplifier. Verified datasheet parameters include 50 MHz unity-gain bandwidth, 350 V/µs slew rate, 15 mA output current per amplifier, and operation on ±5 V to ±15 V dual supplies. It is specified for the industrial temperature range and is available in 8-lead SOIC and 8-lead PDIP packages.
What package and pinout do AD826AR and AD826AR-REEL use?
Both parts use the 8-lead SOIC (R-8) package with the standard dual-op-amp pinout: 1 OUT A, 2 -IN A, 3 +IN A, 4 V-, 5 +IN B, 6 -IN B, 7 OUT B, 8 V+. The package and pinout are identical for both order codes.
Why would a designer choose AD826AR-REEL instead of AD826AR?
AD826AR-REEL is supplied on tape and reel, which is compatible with automated pick-and-place assembly lines and high-volume production. AD826AR in tubes is typically used for prototyping, low-volume runs, or manual assembly. The silicon and specifications are the same.
Can AD826AR and AD826AR-REEL be mixed on the same PCB assembly?
Yes. Because both order codes are the same AD826AR device in the same 8-lead SOIC package with identical pinout and electrical specifications, they can be used interchangeably on the same board. Mixing tube and reel packaging does not affect form, fit, or function.
Do AD826AR and AD826AR-REEL differ in moisture sensitivity or handling requirements?
No. Both are the same 8-lead SOIC device and share the same moisture sensitivity level and handling requirements as specified by the manufacturer for the AD826AR in the R-8 package. Packaging format (tube vs. tape and reel) does not change the device's MSL classification.
What supply voltage range and load conditions apply to both AD826AR and AD826AR-REEL?
Both parts operate from dual supplies of ±5 V to ±15 V and are specified for driving loads such as 150 Ω with the datasheet-rated output current of 15 mA per amplifier. These operating conditions are identical for both order codes because they are the same device.
