Key electrical and mechanical differences between the two devices
| Parameter | AD8275ARMZ | AD8275ARMZ-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 single-channel signal chain. |
| Supply Voltage Range | 3 V to 36 V (single supply) | 3 V to 36 V (single supply) | Identical supply range ensures the part operates correctly in the same power rail configuration. |
| Gain | 0.2 V/V | 0.2 V/V | Fixed gain determines the output scaling; matching gain preserves system transfer function. |
| Input Offset Voltage | ±250 µV (max) | ±250 µV (max) | Offset directly affects DC accuracy; identical offset specs mean equivalent precision performance. |
| Bandwidth | 15 MHz | 15 MHz | Bandwidth governs the maximum signal frequency handled; matching bandwidth ensures equivalent dynamic response. |
| Package / Mounting | 8-Lead MSOP, Surface Mount | 8-Lead MSOP, Surface Mount | Same package and footprint allow direct board-level replacement without layout changes. |
| Packaging / Ordering Format | Tube | Tape & Reel | The only difference is the shipping format; -RL denotes reel packaging for automated assembly, while the base part is tube-packed. |

Frequently asked questions
What is the difference between AD8275ARMZ and AD8275ARMZ-RL?
Both parts are the same AD8275 precision difference amplifier die in an 8-lead MSOP (RM) package. The suffix difference is packaging format: AD8275ARMZ is the standard tube/tray ordering code, while AD8275ARMZ-RL is the tape-and-reel ordering code (RL suffix). Electrical performance and package outline are identical; only the shipping media and order quantity differ.
Are AD8275ARMZ and AD8275ARMZ-RL electrically and functionally interchangeable?
Yes. Both ordering codes refer to the same AD8275 device in the same 8-lead MSOP package with identical pinout and specified performance. They can be used interchangeably in a design; the choice depends on the assembly line's feeding method (tube vs. tape-and-reel).
What is the AD8275 and what are its key verified specifications?
The AD8275 is a precision, low-power difference amplifier from Analog Devices. Verified datasheet parameters include a gain of 0.2 (attenuation), a wide input common-mode voltage range that extends beyond the supply rails, low gain error, and operation from a single 3.3 V to 5 V supply (with a specified supply range per the datasheet). It is intended for level shifting and attenuation of high-voltage signals into ADC inputs.
What package do AD8275ARMZ and AD8275ARMZ-RL use?
Both are supplied in the 8-lead MSOP package, indicated by the "RM" code in the part number. The "Z" suffix denotes RoHS-compliant, lead-free construction per Analog Devices ordering conventions.
Which ordering code should be selected for high-volume automated assembly?
AD8275ARMZ-RL is the tape-and-reel option, which is typically preferred for automated pick-and-place assembly lines. AD8275ARMZ (tube/tray) is generally used for prototyping, low-volume, or manual assembly. Both contain the identical device.
Do AD8275ARMZ and AD8275ARMZ-RL differ in temperature range or qualification?
No. Because both ordering codes refer to the same AD8275 device, they share the same specified operating temperature range and qualification status as stated in the Analog Devices datasheet. Packaging format does not change the device's temperature grade or reliability qualification.
Can AD8275ARMZ and AD8275ARMZ-RL be mixed on the same PCB assembly?
Yes. Since both are the same die in the same 8-lead MSOP package with identical pinout, they are physically and electrically identical on the board. Mixing reel and tube stock does not affect assembly or function, provided both are handled per the manufacturer's moisture sensitivity and soldering guidelines.
