Replacement verdict
Compatible functional replacement candidate
The AD823AR and AD823AR-REEL7 are the same AD823A operational amplifier die offered under two ordering formats, with the REEL7 suffix denoting tape-and-reel packaging rather than any electrical or functional change. Both parts share identical core specifications, making them fully interchangeable for design and production purposes; the only meaningful distinction is the shipping format, which affects handling and assembly logistics rather than circuit performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD823AR | AD823AR-REEL7 | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical silicon design and process, critical for functional substitutability. |
| Amplifier Type | J-FET Input, Rail-to-Rail Output | J-FET Input, Rail-to-Rail Output | Defines the input bias current behavior and output swing capability, which determine circuit compatibility. |
| Number of Channels | 2 | 2 | Channel count must match for pinout and circuit topology compatibility. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | Determines the maximum signal frequency the amplifier can handle with acceptable gain, affecting AC performance. |
| Supply Voltage Range | 3 V to 36 V (±1.5 V to ±18 V) | 3 V to 36 V (±1.5 V to ±18 V) | Must match the system power rails for the part to operate correctly in the target design. |

Frequently asked questions
What is the difference between AD823AR and AD823AR-REEL7?
Both parts are the same AD823 dual operational amplifier die in the same 8-lead SOIC (R-8) package. The difference is packaging format: AD823AR is supplied in standard tube/tray quantities, while AD823AR-REEL7 is supplied on a 7-inch tape-and-reel carrier for automated pick-and-place assembly. Electrical specifications are identical.
Are AD823AR and AD823AR-REEL7 electrically and functionally interchangeable?
Yes. Both are the same AD823 model in the same R-8 SOIC package with identical pinout and specified performance. They differ only in shipping format, so they are interchangeable in the assembled board; the choice depends on the production handling method (manual/tube vs. automated reel).
What are the key specifications of the AD823?
The AD823 is a dual, 16 MHz rail-to-rail FET-input operational amplifier. Verified datasheet parameters include 16 MHz unity-gain bandwidth, 35 V/µs slew rate, single-supply operation from 3 V to 36 V (or dual ±1.5 V to ±18 V), rail-to-rail output, and low input bias current typical of FET input stages. Consult the Analog Devices datasheet for full guaranteed limits over temperature.
What package does the AD823AR use?
The AD823AR and AD823AR-REEL7 are both offered in the 8-lead SOIC package, designated R-8 by Analog Devices. The package is surface-mount and RoHS-compliant per the manufacturer's ordering guide.
Why would a design choose AD823AR-REEL7 instead of AD823AR?
AD823AR-REEL7 is provided on 7-inch tape and reel, which is compatible with automated surface-mount placement equipment and high-volume production lines. AD823AR in tubes is typically used for prototyping, low-volume runs, or manual assembly.
Do AD823AR and AD823AR-REEL7 share the same operating temperature range?
Yes. Both are the same AD823 grade in the same package, so they carry the same specified temperature range as defined in the Analog Devices datasheet for the AD823AR grade. Verify the exact grade limits in the current datasheet before finalizing a design.
Can AD823AR-REEL7 be used as a drop-in replacement for AD823AR on an existing PCB?
Yes, provided the board is designed for the 8-lead SOIC (R-8) footprint. Since both parts are the same die and package with identical pinout, no layout change is required; only the assembly feed method differs.
