Replacement verdict
Compatible functional replacement candidate
The AD736ARZ and AD736AR-REEL7 are functionally equivalent, sharing the same RMS-to-DC converter core, package, and electrical specifications; the only distinction is the packaging format, with the REEL7 variant supplied on tape and reel for automated assembly. Both parts are interchangeable in design and application, and the choice between them should be driven solely by production handling requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD736ARZ | AD736AR-REEL7 | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical silicon design and process, critical for functional substitutability. |
| Function | RMS-to-DC Converter (True RMS) | RMS-to-DC Converter (True RMS) | Both perform the same core signal conversion function, so they are functionally interchangeable. |
| Package / Case | 8-Lead SOIC (R-8) | 8-Lead SOIC (R-8) | Identical package footprint allows drop-in replacement on the same PCB layout. |
| Supply Voltage (Dual) | ±2.8 V to ±16.5 V | ±2.8 V to ±16.5 V | Same supply range means the part works in the same power rails without redesign. |
| Supply Current | 200 µA typical | 200 µA typical | Identical quiescent current keeps power budget and thermal behavior unchanged. |
| Bandwidth | 190 kHz (typical) | 190 kHz (typical) | Same bandwidth supports the same AC signal measurement range. |
| Accuracy / Total Error | ±0.3% max (at 1 kHz) | ±0.3% max (at 1 kHz) | Matching accuracy ensures measurement precision is preserved after substitution. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Same temperature rating means both suit the same environmental conditions. |
| Packaging / Delivery Form | Tube | Tape & Reel (7-inch reel) | Different packaging affects assembly line handling and pick-and-place automation, though the device itself is identical. |

Frequently asked questions
What is the difference between AD736ARZ and AD736AR-REEL7?
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-REEL7 is supplied on a 7-inch tape-and-reel for automated assembly. Electrical specifications are identical per the Analog Devices datasheet.
Are AD736ARZ and AD736AR-REEL7 electrically and functionally interchangeable?
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, so they are interchangeable in circuit design. The only practical difference is the shipping container (tube vs. 7-inch reel).
What is the AD736 and what does it do?
The AD736 is an Analog Devices low power, precision true RMS-to-DC converter that computes the RMS value of an input waveform. It provides an output proportional to the true RMS of the input signal and is suited to AC measurement applications where average-responding converters would be inaccurate.
What package do AD736ARZ and AD736AR-REEL7 use?
Both devices are offered in the 8-lead SOIC package (Analog Devices R-8 suffix). The "R" in the ordering code denotes the SOIC package, and "Z" denotes RoHS-compliant lead finish per Analog Devices ordering conventions.
Are AD736ARZ and AD736AR-REEL7 RoHS compliant?
Yes. The "Z" suffix in both ordering codes indicates RoHS-compliant construction per Analog Devices ordering information. Designers should confirm the current compliance status against the latest manufacturer datasheet or product page before final qualification.
Which part should be selected for high-volume automated PCB assembly?
AD736AR-REEL7 is the appropriate choice for automated pick-and-place lines because it is supplied on a 7-inch tape-and-reel. AD736ARZ in tube form is typically used for prototyping, low-volume runs, or manual assembly.
Do AD736ARZ and AD736AR-REEL7 share the same datasheet and specifications?
Yes. Both ordering codes refer to the same AD736 product family and are covered by the same Analog Devices AD736 datasheet. Electrical characteristics, pinout, and package outline are common to both; only the packaging quantity and delivery format differ.
