Key electrical and mechanical differences between the two devices
| Parameter | AD823ARZ | AD823ARZ-RL | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical design, process, and quality standards. |
| Amplifier Type | J-FET Input, Rail-to-Rail Output | J-FET Input, Rail-to-Rail Output | Defines the input bias characteristics and output swing capability, critical for signal conditioning applications. |
| Number of Channels | 2 | 2 | Dual-channel configuration determines how many independent signal paths can be processed per package. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | Sets the maximum usable frequency for closed-loop gain, directly affecting AC signal fidelity. |
| 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) | Determines compatibility with single-supply and dual-supply system rails. |
| Input Offset Voltage | 800 µV (max) | 800 µV (max) | Affects DC accuracy; lower offset improves precision in low-level signal amplification. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Footprint and mounting style must match for PCB drop-in compatibility. |
| Packaging / Delivery Form | Tube | Tape & Reel | Delivery format affects assembly line handling; tape and reel is required for automated pick-and-place production. |

Frequently asked questions
What is the difference between AD823ARZ and AD823ARZ-RL?
Both parts are the same AD823 dual operational amplifier die in an 8-lead SOIC package. The AD823ARZ is supplied in tube packaging, while the AD823ARZ-RL is supplied in tape-and-reel packaging for automated assembly. Electrical performance and package outline are identical.
Are AD823ARZ and AD823ARZ-RL electrically interchangeable?
Yes. Both variants share the same datasheet specifications, including the 16 MHz gain bandwidth product, 35 V/µs slew rate, and 800 µA supply current per amplifier, so they are electrically interchangeable in the same circuit.
What package do AD823ARZ and AD823ARZ-RL use?
Both are offered in an 8-lead SOIC package (R-8 suffix), with the same pinout and PCB land pattern, so no layout change is required when switching between them.
What is the difference in packaging quantity between AD823ARZ and AD823ARZ-RL?
The AD823ARZ is supplied in tubes, while the AD823ARZ-RL is supplied on a 13-inch tape-and-reel. The reel option is intended for high-volume pick-and-place assembly lines.
Do AD823ARZ and AD823ARZ-RL have the same operating temperature range?
Yes. Both variants are specified over the industrial temperature range of −40°C to +85°C, as stated in the AD823 datasheet.
Can AD823ARZ-RL be used as a drop-in replacement for AD823ARZ in an existing design?
Yes, provided the assembly process supports tape-and-reel feeding. The die, package, pinout, and electrical specifications are the same, so no circuit or layout changes are needed.
Which variant should be selected for prototype versus production builds?
AD823ARZ in tubes is typically convenient for prototyping and hand assembly, while AD823ARZ-RL tape-and-reel is preferred for automated production lines. Selection depends on the assembly method, not on electrical differences.
