Replacement verdict
Compatible functional replacement candidate
The AD829ARZ and AD829AR-REEL7 are functionally equivalent, sharing the same die, package, and specified performance characteristics; the only distinction is the packaging format, with the REEL7 variant supplied on tape and reel for automated assembly. Either part number can serve as a direct substitute for the other in the same application, provided the board assembly process accommodates the respective delivery format.

Key electrical and mechanical differences between the two devices
| Parameter | AD829ARZ | AD829AR-REEL7 | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback Amplifier | Voltage Feedback Amplifier | Confirms both parts share the same core amplifier topology, which is essential for functional substitutability. |
| Number of Circuits | 1 | 1 | Both are single-channel devices, so channel count matches for direct replacement. |
| Package / Case | 8-SOIC | 8-SOIC | Identical package ensures the part fits the same PCB footprint and solder profile. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style guarantees compatibility with the existing board assembly process. |
| Supply Voltage Range | ±4.5 V to ±18 V (dual) | ±4.5 V to ±18 V (dual) | Matching supply range means the part operates correctly in the same circuit power rails. |
| Gain Bandwidth Product | 120 MHz | 120 MHz | Identical bandwidth ensures equivalent AC performance and signal fidelity in the application. |
| Slew Rate | 230 V/µs | 230 V/µs | Same slew rate preserves large-signal transient response and stability characteristics. |
| Input Offset Voltage | 0.5 mV (typ) | 0.5 mV (typ) | Equivalent offset voltage maintains DC accuracy and minimizes output error in precision circuits. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Same temperature range ensures reliable operation across the same environmental conditions. |
| Packaging / Delivery Form | Tube / Bulk | Tape & Reel | Different packaging affects handling and automated assembly; the reel version suits high-volume pick-and-place lines while the tube version suits prototyping or low-volume use. |

Frequently asked questions
What is the difference between AD829ARZ and AD829AR-REEL7?
Both parts are the same AD829 operational amplifier die in an 8-lead SOIC package (R-8 suffix). The AD829ARZ is supplied in tube packaging, while AD829AR-REEL7 is supplied on a 7-inch tape-and-reel carrier for automated assembly. The electrical specifications are identical; only the packaging and ordering quantity differ.
Are AD829ARZ and AD829AR-REEL7 electrically interchangeable?
Yes. Both are the same AD829AR grade device in the same 8-lead SOIC package, so they share identical pinout, supply range, and specified AC/DC performance. The only difference is the shipping container (tube vs. 7-inch reel), so they can be used interchangeably in the same PCB design.
What package do AD829ARZ and AD829AR-REEL7 use?
Both devices are offered in the 8-lead SOIC package (Analog Devices R-8 suffix), a surface-mount package with 1.27 mm lead pitch. The AD829AR-REEL7 is the same package supplied on tape and reel.
Which part should be selected for automated SMT production?
AD829AR-REEL7 is the appropriate choice for automated surface-mount assembly because it is supplied on a 7-inch tape-and-reel carrier compatible with pick-and-place equipment. AD829ARZ in tubes is typically used for prototyping, low-volume, or manual assembly.
Do AD829ARZ and AD829AR-REEL7 have the same temperature range and grade?
Yes. Both are the AR grade of the AD829, specified over the commercial temperature range of 0°C to +70°C. The grade and temperature specification are determined by the part number prefix (AD829AR), not by the packaging suffix.
Is the AD829 a high-speed operational amplifier suitable for video applications?
Yes. The AD829 is a low-noise, high-speed operational amplifier with a typical unity-gain bandwidth of 120 MHz and a slew rate of approximately 230 V/µs, making it suitable for video and other high-speed signal-processing applications. Both AD829ARZ and AD829AR-REEL7 share these characteristics.
Can AD829ARZ and AD829AR-REEL7 be used as drop-in replacements for each other on an existing board?
Yes, from an electrical and footprint standpoint they are drop-in replacements because they are the same die in the same 8-lead SOIC package. The choice between them is purely a matter of procurement packaging (tube vs. 7-inch reel) and does not affect board-level performance.
