Replacement verdict
Compatible functional replacement candidate
The AD823AR and AD823AR-REEL are functionally identical dual 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 package type, making them fully interchangeable for design and performance purposes, while procurement and inventory planning should account for the differing packaging presentation.

Key electrical and mechanical differences between the two devices
| Parameter | AD823AR | AD823AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | J-FET Input, Rail-to-Rail Output | J-FET Input, Rail-to-Rail Output | Defines the input topology and output swing capability, which determine signal compatibility in a circuit. |
| Number of Channels | 2 | 2 | Channel count must match the circuit design for dual op-amp applications. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | Determines the maximum frequency range over which the amplifier provides useful gain. |
| Slew Rate | 22 V/µs | 22 V/µs | Affects the ability to handle fast transients and large-signal high-frequency signals. |
| Input Offset Voltage | 0.8 mV (typ) | 0.8 mV (typ) | Low offset improves DC accuracy in precision signal-conditioning applications. |
| 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 be compatible with the system power rails for proper operation. |
| Input Bias Current | 5 pA (typ) | 5 pA (typ) | Very low bias current is critical for high-impedance sensor and photodiode interfaces. |
| Package / Mounting | 8-Lead SOIC (Surface Mount) | 8-Lead SOIC (Surface Mount), Tape & Reel | Package and packaging format affect PCB footprint and assembly/pick-and-place handling; the reel version is supplied on tape for automated production. |
| Packaging Format | Tube / Cut Tape | Tape & Reel | The delivery format differs; tape and reel is suited for high-volume automated assembly, while tube is common for prototyping and low-volume use. |

Frequently asked questions
What is the difference between AD823AR and AD823AR-REEL?
The AD823AR and AD823AR-REEL are the same AD823 dual operational amplifier die in the same 8-lead SOIC (R-8) package. The suffix "-REEL" designates tape-and-reel packaging for automated assembly, while the base AD823AR part number denotes standard packaging (typically tube/rail). Electrical specifications are identical between the two ordering options.
Are AD823AR and AD823AR-REEL electrically and functionally interchangeable?
Yes. Both ordering codes refer to the same AD823AR grade device: a dual, 16 MHz, rail-to-rail FET-input operational amplifier in an 8-lead SOIC package. Because the silicon, grade, and package are identical, they are electrically and functionally interchangeable; only the shipping/packaging format differs.
What package and pinout do AD823AR and AD823AR-REEL use?
Both parts are supplied in the 8-lead SOIC (R-8) package. The pinout is the standard dual op-amp SOIC configuration: pin 1 = OUT A, pin 2 = -IN A, pin 3 = +IN A, pin 4 = V-, pin 5 = +IN B, pin 6 = -IN B, pin 7 = OUT B, and pin 8 = V+. The PCB land pattern is identical for both ordering codes.
Which packaging format should I choose, AD823AR or AD823AR-REEL?
Choose AD823AR-REEL when using automated pick-and-place assembly lines that require tape-and-reel feed; choose AD823AR when tube/rail packaging suits manual or low-volume assembly. The decision is purely a manufacturing/logistics consideration, since the device itself is the same.
Do AD823AR and AD823AR-REEL share the same operating temperature range and supply specifications?
Yes. As the same AD823AR grade device, both ordering codes share identical specifications, including the specified operating temperature range and supply voltage range per the Analog Devices AD823 datasheet. Packaging format does not affect these ratings.
Can AD823AR and AD823AR-REEL be mixed on the same PCB assembly?
Yes. Since both are the same AD823AR device in the same 8-lead SOIC package with identical pinout and electrical specifications, they can be used interchangeably on the same board. Any mix is a packaging/logistics choice, not an electrical one.
Is the AD823AR-REEL a different grade or revision of the AD823AR?
No. The "-REEL" suffix denotes tape-and-reel delivery format only; it does not indicate a different grade, speed, temperature range, or silicon revision. Both ordering codes correspond to the AD823AR grade of the AD823 dual FET-input op amp.
