Key electrical and mechanical differences between the two devices
| Parameter | AD8475ARMZ | AD8475ARMZ-RL | Why it matters |
|---|---|---|---|
| Amplifier Type | Differential / Fully Differential Amplifier | Differential / Fully 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 | 3 V to 10 V (single supply) | 3 V to 10 V (single supply) | Identical supply range ensures the same power rail can be used without redesign. |
| Gain | 0.4 (fixed, pin-selectable 0.8) | 0.4 (fixed, pin-selectable 0.8) | Matching attenuation/gain settings preserve the signal scaling of the application. |
| Bandwidth | 150 MHz (-3 dB) | 150 MHz (-3 dB) | Same bandwidth means identical frequency response and dynamic performance. |
| Package / Case | 10-Lead MSOP (RM-10) | 10-Lead MSOP (RM-10) | Identical package footprint allows direct board replacement without layout changes. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style is required for physical compatibility on the PCB. |
| Packaging / Reel | Tube / Tray (cut tape) | Tape & Reel | The "-RL" suffix denotes tape-and-reel packaging, which matters for automated assembly but not electrical function. |
| Ordering Quantity | Single units / small quantities | Full reel (e.g., 5000 units) | Ordering quantity differs due to packaging, affecting procurement and production planning, not performance. |

Frequently asked questions
What is the difference between AD8475ARMZ and AD8475ARMZ-RL?
Both parts are the same AD8475 differential amplifier die in an 8-lead MSOP (RM) package. The suffix difference is packaging format: AD8475ARMZ is supplied in standard tube/rail packaging, while AD8475ARMZ-RL is supplied in tape-and-reel packaging for automated assembly. Electrical performance and package outline are identical.
Are AD8475ARMZ and AD8475ARMZ-RL electrically and functionally interchangeable?
Yes. Both order codes refer to the same AD8475 device in the same 8-lead MSOP package, so they are electrically and functionally interchangeable. The only difference is the shipping packaging (tube vs. tape-and-reel).
What is the AD8475 and what are its key verified specifications?
The AD8475 is an Analog Devices precision, low-power, fully differential funnel amplifier with integrated precision gain resistors. Verified datasheet parameters include a 5 V single-supply operation, selectable gains of 0.4 and 0.8, a bandwidth of 150 MHz (G = 0.4), and an 8-lead MSOP package. It is designed to drive differential-input ADCs.
What package does the AD8475ARMZ use and is it RoHS compliant?
The AD8475ARMZ and AD8475ARMZ-RL both use the 8-lead MSOP package (RM suffix). The "Z" suffix in the Analog Devices part numbering denotes RoHS-compliant, lead-free construction.
Which part should be selected for high-volume automated PCB assembly?
AD8475ARMZ-RL should be selected for automated pick-and-place assembly because it is supplied in tape-and-reel format. AD8475ARMZ in tube/rail packaging is typically used for prototyping, low-volume, or manual assembly.
Do AD8475ARMZ and AD8475ARMZ-RL share the same operating temperature range?
Yes. Since both order codes refer to the same AD8475 device, they share the same specified operating temperature range as defined in the Analog Devices datasheet. The packaging format does not affect the temperature specification.
Can the AD8475 drive a differential-input ADC directly?
Yes. The AD8475 is a fully differential funnel amplifier with integrated precision gain resistors, designed specifically to attenuate and level-shift single-ended or differential signals to drive differential-input ADCs. Refer to the Analog Devices datasheet for the specific ADC interface and gain configuration details.
