Key electrical and mechanical differences between the two devices
| Parameter | AD623BRZ-R7 | AD623BRZ-RL | Why it matters |
|---|---|---|---|
| Amplifier Type | Instrumentation Amplifier | Instrumentation Amplifier | Both parts are the same core instrumentation amplifier, so the fundamental function is identical. |
| Number of Circuits | 1 | 1 | Single-channel configuration must match for direct circuit substitution. |
| Package / Case | 8-SOIC | 8-SOIC | Identical package ensures the part fits the same PCB footprint. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style is required for assembly compatibility. |
| Supply Voltage Range | 2.7 V to 12 V | 2.7 V to 12 V | Matching supply range confirms the parts operate in the same system voltage conditions. |
| Gain Bandwidth Product | 800 kHz | 800 kHz | Identical bandwidth ensures equivalent signal conditioning performance. |
| Input Offset Voltage | 200 µV (max) | 200 µV (max) | Same offset voltage spec means comparable DC accuracy in precision measurement applications. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings confirm both parts suit the same environmental conditions. |
| Packaging / Reel Size | 7-inch reel (R7) | 13-inch reel (RL) | The reel size differs, which affects pick-and-place feeder setup and order quantity, though the parts themselves are functionally identical. |

Frequently asked questions
What is the difference between AD623BRZ-R7 and AD623BRZ-RL?
Both are the same AD623 instrumentation amplifier in an 8-lead SOIC package (R-8 suffix) with the B grade (0.1% gain error, 2 µV/°C max offset drift) and RoHS-compliant Z material. The only difference is the packaging format: AD623BRZ-R7 is supplied in 7-inch reels with 750 pieces per reel, while AD623BRZ-RL is supplied in 13-inch reels with 2,500 pieces per reel.
Are AD623BRZ-R7 and AD623BRZ-RL electrically and functionally identical?
Yes. Both part numbers share the same die, grade, and package, so all datasheet parameters are identical, including gain range of 1 to 1000 set by a single external resistor, 800 kHz bandwidth at G = 1, 0.1% max gain error at G = 1, 2 µV/°C max input offset drift, 25 nV/√Hz input voltage noise, and 550 µA max supply current over a 2.7 V to 12 V single-supply or ±2.5 V to ±6 V dual-supply range.
Can AD623BRZ-R7 and AD623BRZ-RL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same AD623BRZ device in the same 8-lead SOIC package. The choice between them is purely a manufacturing decision based on reel size and the pick-and-place equipment's reel capacity.
Which reel size should be selected for high-volume production?
AD623BRZ-RL is typically preferred for high-volume SMT lines because its 13-inch reel carries 2,500 units, reducing reel-change frequency and downtime compared with the 750-unit 7-inch reel of AD623BRZ-R7. AD623BRZ-R7 is better suited to prototyping, low-volume runs, or feeders that accept only 7-inch reels.
Do both parts meet the same moisture sensitivity and soldering requirements?
Yes. Since both are the same AD623BRZ device in the same SOIC package, they share the same moisture sensitivity level and reflow soldering profile specified in the Analog Devices datasheet and packaging documentation. Reel size does not affect MSL classification or the recommended reflow conditions.
Are AD623BRZ-R7 and AD623BRZ-RL both RoHS compliant?
Yes. The "Z" in both part numbers denotes the RoHS-compliant material set used by Analog Devices for the AD623 in the SOIC package, so both the R7 and RL ordering variants are RoHS compliant.
What is the difference between the R7 and RL suffixes in Analog Devices ordering codes?
In Analog Devices ordering nomenclature, the suffix after the package and grade code indicates the shipping container: R7 denotes a 7-inch reel, and RL denotes a 13-inch reel. The base part number AD623BRZ, which defines the device, grade, and package, is unchanged between the two variants.
