Replacement verdict

Compatible functional replacement candidate

The AD8307ARZ and AD8307ARZ-RL7 are the same AD8307 logarithmic amplifier die offered in identical 8-lead SOIC packaging, differing only in factory packing format (tube vs. tape-and-reel). They are functionally interchangeable for design, prototyping, and production use, with the -RL7 variant suited to automated SMT assembly lines.

Key electrical and mechanical differences between the two devices

Parameter AD8307ARZ AD8307ARZ-RL7 Why it matters
Function Logarithmic amplifier / RF detector Logarithmic amplifier / RF detector Both parts perform the same core signal-detection function, so they are functionally interchangeable.
Frequency Range DC to 500 MHz DC to 500 MHz The operating bandwidth determines which RF systems the detector can be used in; identical range means equivalent application coverage.
Dynamic Range 92 dB 92 dB Dynamic range defines the span of input signal levels the detector can measure accurately; matching values ensure equivalent measurement capability.
Logarithmic Slope 25 mV/dB 25 mV/dB The slope sets the output voltage change per dB of input, affecting calibration and downstream ADC scaling; identical slope means no recalibration is needed.
Supply Voltage 2.7 V to 5.5 V 2.7 V to 5.5 V Supply range determines compatibility with the system power rail; identical range means the same power supply can be used.
Supply Current 7.5 mA (typical) 7.5 mA (typical) Quiescent current affects power budget and thermal design; matching values ensure equivalent power consumption.
Package / Mounting 8-Lead SOIC (surface mount) 8-Lead SOIC (surface mount) Package and mounting style must match the PCB footprint; identical packages allow drop-in replacement.
Packaging / Ordering Format Tube Tape & Reel (RL7) The only difference is the shipping format; tape and reel suits automated assembly lines while tubes suit manual or low-volume handling, but the device itself is identical.

Frequently asked questions

What is the difference between AD8307ARZ and AD8307ARZ-RL7?

Both parts are the same AD8307 500 MHz, 92 dB logarithmic amplifier die in an 8-lead SOIC package. The difference is packaging format: AD8307ARZ is supplied in tube/tray quantities, while AD8307ARZ-RL7 is supplied on a 7-inch tape-and-reel for automated assembly. Electrical performance is identical.

Are AD8307ARZ and AD8307ARZ-RL7 electrically and functionally interchangeable?

Yes. Both share the same datasheet specifications, including a 500 MHz bandwidth, 92 dB dynamic range, 25 mV/dB nominal slope, and 2.7 V to 5.5 V single-supply operation. The only distinction is the shipping container, so they are interchangeable in circuit design.

What package do AD8307ARZ and AD8307ARZ-RL7 use?

Both are offered in an 8-lead SOIC package (R-8 suffix), with an operating temperature range of −40 °C to +85 °C. The package and pinout are identical between the two orderable part numbers.

Which part should be selected for high-volume automated PCB assembly?

AD8307ARZ-RL7 is the tape-and-reel option (7-inch reel) and is intended for automated pick-and-place production lines. AD8307ARZ in tubes is typically used for prototyping, low-volume runs, or manual assembly.

Do AD8307ARZ and AD8307ARZ-RL7 differ in moisture sensitivity or handling requirements?

No. Because both are the same SOIC-8 device, they share the same moisture sensitivity level and handling requirements as specified in the manufacturer's datasheet and packaging documentation. Reel versus tube format does not change the device-level MSL classification.

Can AD8307ARZ and AD8307ARZ-RL7 be mixed on the same bill of materials?

They can be treated as the same electrical line item, but the packaging quantity differs. For BOM and inventory control, keep them as separate orderable part numbers so reel quantities and tube quantities are tracked correctly, even though the devices are functionally identical.

What are the key verified specifications shared by AD8307ARZ and AD8307ARZ-RL7?

Both are monolithic logarithmic amplifiers with a 500 MHz bandwidth, 92 dB dynamic range, 25 mV/dB nominal logarithmic slope, and operation from a single 2.7 V to 5.5 V supply. These parameters are common to both orderable part numbers because they use the same silicon and package.
