Replacement verdict
Compatible functional replacement candidate
The AD736ARZ and AD736AR-REEL are functionally equivalent implementations of the same AD736 true RMS-to-DC converter die, differing only in packaging format and shipment presentation. Both parts share identical electrical specifications, pinout, and operating conditions, making them interchangeable in the same application circuit. The primary distinction is the delivery form: the AD736ARZ is supplied in tube/rail packaging, while the AD736AR-REEL is supplied on tape-and-reel for automated assembly. Designers should confirm the packaging format matches their production handling requirements before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | AD736ARZ | AD736AR-REEL | Why it matters |
|---|---|---|---|
| Function | RMS-to-DC Converter (True RMS) | RMS-to-DC Converter (True RMS) | Both parts perform the same core signal-processing function, so they are functionally interchangeable in RMS measurement circuits. |
| Package / Case | 8-Lead SOIC (R-8) | 8-Lead SOIC (R-8) | Identical package and footprint allow drop-in replacement on the same PCB without layout changes. |
| Supply Voltage Range | ±2.8 V to ±16.5 V (dual) or 2.8 V to 16.5 V (single) | ±2.8 V to ±16.5 V (dual) or 2.8 V to 16.5 V (single) | Matching supply ranges ensure both parts operate correctly in the same power architecture. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings confirm both parts suit the same environmental conditions. |
| Accuracy (RMS) | ±0.3% max (0.1% typical) at 1 kHz | ±0.3% max (0.1% typical) at 1 kHz | Measurement accuracy is a key performance metric; identical accuracy means equivalent measurement quality. |
| Bandwidth | 200 kHz (-3 dB) | 200 kHz (-3 dB) | Same bandwidth supports the same input signal frequency range in both parts. |
| Supply Current | 200 µA typical | 200 µA typical | Equal quiescent current means identical power budget impact in the application. |
| Packaging / Delivery Form | Tube / cut tape (individual) | Tape and reel (13-inch reel) | The delivery form differs: the reel version suits automated high-volume SMT assembly, while the tube version suits prototyping or low-volume runs. The die and performance are the same. |
| Ordering Part Number Suffix | AD736ARZ (Z = RoHS-compliant) | AD736AR-REEL (reel packaging) | The suffix indicates packaging and compliance differences; both are the same silicon device but ordered under different part numbers for logistics. |

Frequently asked questions
What is the difference between AD736ARZ and AD736AR-REEL?
Both parts are the same AD736 true RMS-to-DC converter die in an 8-lead SOIC package. The difference is packaging format: AD736ARZ is supplied in tube/tray quantities, while AD736AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix on AD736ARZ denotes RoHS-compliant lead finish per Analog Devices nomenclature.
Are AD736ARZ and AD736AR-REEL electrically and functionally identical?
Yes. Both are the AD736 true RMS-to-DC converter in the 8-lead SOIC (R-8) package with the same pinout and specified performance. They differ only in shipping container (tube vs. tape-and-reel), not in electrical specifications.
What is the AD736 and what does it do?
The AD736 is an Analog Devices low-cost, low-power true RMS-to-DC converter that computes the RMS value of complex input waveforms. It provides a DC output proportional to the true RMS of the input signal and is suited for applications such as RMS metering and signal measurement.
What package do AD736ARZ and AD736AR-REEL use?
Both are offered in the 8-lead SOIC package (Analog Devices R-8 suffix). The package and pinout are identical between the two ordering codes.
Can AD736AR-REEL be used as a drop-in replacement for AD736ARZ?
Yes, from an electrical and footprint standpoint they are the same device in the same 8-lead SOIC package. The only practical difference is delivery format: tape-and-reel versus tube/tray. Verify the RoHS/lead-finish designation required by your assembly process against the specific ordering code.
Which part should be selected for high-volume automated PCB assembly?
AD736AR-REEL is the appropriate choice for automated pick-and-place assembly because it is supplied on tape-and-reel. AD736ARZ in tube/tray format is typically used for low-volume, prototyping, or manual assembly.
Do AD736ARZ and AD736AR-REEL differ in RoHS compliance?
The "Z" suffix in AD736ARZ indicates RoHS-compliant construction per Analog Devices part-numbering convention. Buyers should confirm the RoHS status of the specific AD736AR-REEL ordering code against the manufacturer datasheet or distributor documentation before assuming equivalence.
