Replacement verdict
Compatible functional replacement candidate
The AD8306AR and AD8306AR-REEL are functionally identical, as the -REEL suffix denotes tape-and-reel packaging of the same AD8306AR device. Both share the same die, electrical specifications, and 16-lead SOIC package, making them interchangeable for design and qualification purposes. The only meaningful distinction is the shipping format, which affects procurement and assembly handling rather than electrical performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD8306AR | AD8306AR-REEL | Why it matters |
|---|---|---|---|
| Function | 5 MHz to 400 MHz, 100 dB Demodulating Logarithmic Amplifier | 5 MHz to 400 MHz, 100 dB Demodulating Logarithmic Amplifier | Confirms both parts provide the same core signal-processing function, so they are functionally interchangeable. |
| Package / Case | 16-Lead SOIC (R-16) | 16-Lead SOIC (R-16) | Identical package ensures the same PCB footprint and assembly process can be used. |
| Frequency Range | 5 MHz to 400 MHz | 5 MHz to 400 MHz | Operating frequency range must match for the part to work in the target RF/IF signal chain. |
| Dynamic Range | 100 dB | 100 dB | Logarithmic amplifier dynamic range determines the measurable signal span and accuracy of RSSI/level detection. |
| Supply Voltage | 2.7 V to 6.5 V | 2.7 V to 6.5 V | Supply range must be compatible with the system rail for correct biasing and operation. |
| Supply Current | 16 mA typical | 16 mA typical | Quiescent current affects power budget and thermal design in the application. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment for reliable performance. |
| Packaging / Delivery Form | Tube / individual cut tape | Tape and reel (reel packaging) | Delivery form affects handling and suitability for automated high-volume SMT assembly lines. |

Frequently asked questions
What is the difference between AD8306AR and AD8306AR-REEL?
The AD8306AR and AD8306AR-REEL are the same device: the AD8306 5 MHz to 400 MHz, 100 dB logarithmic amplifier. The difference is packaging format. AD8306AR is supplied in tube or individual tray quantities, while AD8306AR-REEL is supplied on tape and reel for automated surface-mount assembly. Both use the same 16-lead SOIC package and have identical electrical specifications.
Are AD8306AR and AD8306AR-REEL electrically and functionally identical?
Yes. Both part numbers refer to the same AD8306 logarithmic amplifier die in the same 16-lead SOIC package. The electrical specifications, pinout, and functional behavior are identical. The suffix difference only indicates the shipping container format (tube/tray versus tape and reel).
What package do AD8306AR and AD8306AR-REEL use?
Both AD8306AR and AD8306AR-REEL are offered in a 16-lead SOIC package (R-16 suffix). The package body and pin configuration are the same for both ordering options.
Can AD8306AR-REEL be used as a drop-in replacement for AD8306AR?
Yes, from an electrical and mechanical standpoint the devices are identical. AD8306AR-REEL can replace AD8306AR in an existing design provided the assembly process supports tape-and-reel feeding. No circuit or layout changes are required.
Why would a designer choose AD8306AR-REEL over AD8306AR?
AD8306AR-REEL is intended for high-volume automated surface-mount assembly lines that require tape-and-reel packaging for pick-and-place equipment. AD8306AR in tube or tray form is typically used for prototyping, low-volume runs, or manual assembly.
What are the key specifications of the AD8306?
The AD8306 is a complete monolithic logarithmic amplifier operating from 5 MHz to 400 MHz with a 100 dB dynamic range. It provides a nominal logarithmic slope of 20 mV/dB and an intercept of approximately -95 dBm, and operates from a single 2.7 V to 6.5 V supply. These specifications apply equally to AD8306AR and AD8306AR-REEL.
Do AD8306AR and AD8306AR-REEL differ in operating temperature range or qualification?
No. Both ordering options correspond to the same industrial-grade AD8306 device and share the same specified operating temperature range and qualification status. The ordering suffix reflects packaging only, not temperature grade or reliability screening.
