Replacement verdict
Compatible functional replacement candidate
The AD823AARZ and AD823AR-REEL are functionally equivalent dual operational amplifiers sharing the same core architecture, package footprint, and supply requirements, making them suitable substitutes in most designs. The primary distinction lies in packaging format and sourcing channel rather than electrical performance, so the AD823AARZ can serve as a direct functional replacement for the AD823AR-REEL where reel packaging is not mandatory.

Key electrical and mechanical differences between the two devices
| Parameter | AD823AARZ | AD823AR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | J-FET Input, Rail-to-Rail Output | J-FET Input, Rail-to-Rail Output | Both are J-FET input rail-to-rail output op amps, so the core amplifier topology is functionally equivalent. |
| Number of Channels | 2 (Dual) | 2 (Dual) | Channel count must match for pin-compatible substitution in dual-amplifier circuits. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | GBW determines the maximum usable signal frequency and closed-loop bandwidth; matching values preserve AC performance. |
| Slew Rate | 22 V/µs | 22 V/µs | Slew rate limits large-signal response; identical slew rates ensure equivalent transient behavior. |
| Input Offset Voltage (Max) | 800 µV | 800 µV | Offset voltage affects DC accuracy; matching maximum offset supports equivalent precision in signal chains. |
| 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) | Compatible supply range ensures the part can operate in the same power rails without redesign. |
| Input Bias Current | 25 pA (typ) | 25 pA (typ) | Low input bias current is critical for high-impedance sensor interfaces; matching values preserve input loading characteristics. |
| Package / Mounting | 8-Lead SOIC (Surface Mount) | 8-Lead SOIC (Surface Mount, Tape & Reel) | Same package and footprint allow drop-in board replacement; the reel variant only differs in shipping format. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure equivalent environmental robustness for industrial applications. |

Frequently asked questions
What are the key differences between the AD823AARZ and the AD823AR-REEL?
Both devices are dual, 16 MHz, rail-to-rail FET-input operational amplifiers from Analog Devices in an 8-lead SOIC package. The AD823AARZ is supplied in tube form, while the AD823AR-REEL is supplied on a 7-inch tape-and-reel carrier for automated assembly. The AD823AARZ is the RoHS-compliant version of the AD823A, whereas the AD823AR-REEL is the non-RoHS AD823A ordering option.
Are the AD823AARZ and AD823AR-REEL electrically identical?
Yes. Both ordering codes refer to the same AD823A die and the same 8-lead SOIC package, so the electrical specifications (16 MHz gain bandwidth, 35 V/µs slew rate, rail-to-rail output, FET input) are identical. The differences are limited to packaging format and RoHS compliance status.
Can the AD823AARZ be used as a drop-in replacement for the AD823AR-REEL?
Yes, from a footprint and electrical standpoint the two parts are interchangeable because they share the same 8-lead SOIC package and the same AD823A silicon. The substitution should still be validated against the target design's assembly and compliance requirements, since the AD823AARZ is RoHS-compliant and the AD823AR-REEL is not.
What package do the AD823AARZ and AD823AR-REEL use?
Both parts are offered in the 8-lead SOIC (Small Outline Integrated Circuit) package, designated by the "R" suffix in the ordering code. The package is surface-mount and suitable for automated pick-and-place assembly.
Which part should be selected for automated production lines?
The AD823AR-REEL is supplied on tape-and-reel, which is the preferred format for high-volume automated pick-and-place assembly. The AD823AARZ is supplied in tubes, which is more typical for prototyping, low-volume runs, or manual handling.
Does the AD823AARZ meet RoHS requirements while the AD823AR-REEL does not?
Yes. The "Z" suffix in AD823AARZ indicates the RoHS-compliant ordering option, while the AD823AR-REEL is the non-RoHS version. Designs targeting RoHS compliance should specify the AD823AARZ or another RoHS-compliant ordering code.
What are the main performance characteristics shared by both parts?
Both the AD823AARZ and AD823AR-REEL are dual FET-input operational amplifiers with 16 MHz gain bandwidth, 35 V/µs slew rate, rail-to-rail output swing, and low input bias current. They are intended for high-speed signal conditioning, active filtering, and ADC driving applications.
