Replacement verdict
Compatible functional replacement candidate
The AD823ARZ-RL and AD823AARZ are functionally equivalent dual operational amplifiers sharing the same core amplifier architecture, package footprint, and supply requirements, making the AD823AARZ a viable functional replacement candidate for the AD823ARZ-RL in most dual-op-amp signal conditioning applications. Designers should confirm grade-specific specifications such as offset voltage and temperature performance against their application requirements before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | AD823ARZ-RL | AD823AARZ | 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 for signal conditioning. |
| Number of Channels | 2 | 2 | Channel count must match for drop-in replacement in dual-amplifier circuits. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | GBW determines the maximum usable frequency for closed-loop gain; matching values preserve AC performance. |
| Slew Rate | 22 V/µs | 22 V/µs | Slew rate limits large-signal bandwidth; identical slew rates ensure equivalent transient response. |
| Input Offset Voltage (Max) | 800 µV | 800 µV | Offset voltage affects DC accuracy; matching maximum offset supports equivalent precision in DC-coupled designs. |
| 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 ranges allow the parts to operate in the same power rails without redesign. |
| Input Bias Current (Typ) | 5 pA | 5 pA | Low input bias current is critical for high-impedance sensor interfaces; matching values preserve input loading behavior. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Identical package and mounting style enable direct PCB footprint compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ratings ensure equivalent environmental robustness for industrial applications. |

Frequently asked questions
What are the key differences between the AD823ARZ-RL and the AD823AARZ?
Both devices are dual, 16 MHz, rail-to-rail FET-input operational amplifiers from Analog Devices in an 8-lead SOIC package. The AD823ARZ-RL is the tape-and-reel packaging variant of the standard AD823A grade, while the AD823AARZ is the tube/rail packaging variant of the same AD823A grade. The core die, electrical specifications, and functional performance are identical; the difference is packaging format and ordering quantity.
Are the AD823ARZ-RL and AD823AARZ electrically and functionally interchangeable?
Yes. Both parts share the same AD823A grade die and the same 8-lead SOIC (R-8) package, with identical pinout, supply range (±1.5 V to ±15 V or 3 V to 30 V single supply), 16 MHz gain bandwidth, and rail-to-rail output. They differ only in shipping format (reel vs. tube), so they are interchangeable in a given design provided the assembly process accommodates the respective packaging.
What does the "-RL" suffix indicate on the AD823ARZ-RL?
The "-RL" suffix denotes tape-and-reel packaging, which is the standard format for automated surface-mount assembly lines. The AD823ARZ-RL is supplied on 7-inch reels with a defined quantity per reel, whereas the AD823AARZ is supplied in anti-static tubes for manual or low-volume assembly.
What is the package and pinout of both devices?
Both the AD823ARZ-RL and AD823AARZ are offered in an 8-lead SOIC (R-8) package. The pinout is: 1 = OUT1, 2 = -IN1, 3 = +IN1, 4 = V-, 5 = +IN2, 6 = -IN2, 7 = OUT2, 8 = V+. This pinout is identical for both ordering variants.
What are the key AC and DC specifications shared by both parts?
Both devices feature a 16 MHz unity-gain bandwidth, 25 V/µs slew rate, rail-to-rail output swing, FET input with low input bias current (typically 5 pA), and low input offset voltage. They operate from ±1.5 V to ±15 V dual supplies or 3 V to 30 V single supply, making them suitable for high-speed signal conditioning, active filters, and ADC driving.
Which variant should be selected for high-volume automated PCB assembly?
The AD823ARZ-RL is the appropriate choice for high-volume automated surface-mount assembly because its tape-and-reel format is compatible with pick-and-place equipment. The AD823AARZ tube format is better suited to prototyping, low-volume runs, or manual assembly.
Do both parts carry the same temperature range and qualification?
Yes. Both the AD823ARZ-RL and AD823AARZ are specified over the industrial temperature range of -40 °C to +85 °C and are RoHS-compliant, as indicated by the "Z" suffix in the part number. Qualification and reliability data are common to the AD823A grade regardless of packaging variant.
