Key electrical and mechanical differences between the two devices
| Parameter | AD8276ARZ | AD8276ARZ-RL | Why it matters |
|---|---|---|---|
| Amplifier Type | Differential Amplifier | Differential Amplifier | Confirms both parts perform the same core signal-conditioning function, so they are functionally interchangeable. |
| Number of Channels | 1 | 1 | Channel count must match for the parts to be drop-in substitutes in a given circuit. |
| Supply Voltage Range | 2.7 V to 36 V (±1.35 V to ±18 V) | 2.7 V to 36 V (±1.35 V to ±18 V) | Identical supply range ensures the part works in the same power rails without redesign. |
| Gain | Fixed gain of 1 (unity) | Fixed gain of 1 (unity) | Fixed unity gain means the transfer function is identical, preserving circuit behavior. |
| Input Offset Voltage | ±100 µV (typ) | ±100 µV (typ) | Offset directly affects DC accuracy; matching values ensure equivalent precision performance. |
| Bandwidth (Gain = 1) | 550 kHz | 550 kHz | Bandwidth determines the maximum signal frequency the amplifier can handle accurately. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Same package and footprint allow direct board-level replacement without layout changes. |
| Packaging / Delivery Form | Tube | Tape & Reel | The only difference is the shipping form; -RL denotes reel packaging for automated assembly, while the base part ships in tubes. |

Frequently asked questions
What is the difference between AD8276ARZ and AD8276ARZ-RL?
The AD8276ARZ and AD8276ARZ-RL are the same AD8276 precision difference amplifier die in an 8-lead SOIC package. The suffix difference is packaging format: AD8276ARZ is supplied in standard tube packaging, while AD8276ARZ-RL is supplied in tape-and-reel packaging for automated assembly. Electrical performance and specifications are identical.
Are AD8276ARZ and AD8276ARZ-RL electrically and functionally interchangeable?
Yes. Both orderable part numbers refer to the same AD8276 difference amplifier with identical electrical specifications, pinout, and 8-lead SOIC (R-8) package. The only distinction is the shipping/packaging format (tube vs. tape-and-reel), so they are interchangeable in the assembled design.
What is the AD8276 and what are its key verified specifications?
The AD8276 is a low power, unity-gain difference amplifier from Analog Devices. Verified datasheet specifications include a wide supply range of ±2 V to ±18 V (or 4 V to 36 V single supply), low supply current of approximately 200 µA maximum, and operation over the −40 °C to +85 °C industrial temperature range. It is offered in an 8-lead SOIC package.
What package does the AD8276ARZ use, and is it RoHS compliant?
The AD8276ARZ and AD8276ARZ-RL are both supplied in the 8-lead SOIC package (Analog Devices package code R-8). The "Z" suffix in the part number denotes a RoHS-compliant, lead-free finish per Analog Devices ordering nomenclature.
Why would a designer choose the AD8276ARZ-RL instead of the AD8276ARZ?
The AD8276ARZ-RL tape-and-reel format is intended for high-volume automated pick-and-place assembly lines, while the AD8276ARZ tube format is typically used for prototyping, low-volume runs, or manual handling. Selection is based on manufacturing packaging requirements, not electrical performance.
What is the supply voltage range and quiescent current of the AD8276?
Per the Analog Devices datasheet, the AD8276 operates from a dual supply of ±2 V to ±18 V or a single supply of 4 V to 36 V. Its maximum supply current is approximately 200 µA, making it suitable for low-power precision signal conditioning.
Can the AD8276ARZ and AD8276ARZ-RL be used in precision difference amplifier applications?
Yes. The AD8276 is a unity-gain difference amplifier designed for precision signal conditioning, with verified datasheet characteristics including low offset voltage and low gain error, making both orderable variants suitable for difference amplification and level-shifting applications within their specified supply and temperature ranges.
