Replacement verdict
Compatible functional replacement candidate
The AD9220AR and AD9220ARS-REEL are functionally equivalent, sharing the same 12-bit ADC core, 28-pin SSOP package, and full commercial temperature range, with the only meaningful distinction being the REEL suffix denoting tape-and-reel packaging for automated assembly. Buyers can treat these as interchangeable for design and qualification purposes, while confirming reel quantity and packaging format against their SMT line requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD9220AR | AD9220ARS-REEL | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Both parts provide the same 12-bit conversion accuracy, so resolution is not a differentiator for substitutability. |
| Sampling Rate | 10 MSPS | 10 MSPS | Identical maximum sampling rate means both can handle the same signal bandwidth and throughput requirements. |
| Number of Inputs | 1 | 1 | Both are single-channel ADCs, so channel count matches for the same application. |
| Input Type | Differential, Single-Ended | Differential, Single-Ended | Same input configuration supports identical analog front-end designs. |
| Data Interface | Parallel | Parallel | Both use a parallel output interface, so the digital host connection is interchangeable. |
| Supply Voltage | 5 V (Analog and Digital) | 5 V (Analog and Digital) | Matching supply requirements allow the same power rail design to be reused. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings ensure both parts suit the same environmental conditions. |
| Package / Mounting Type | 28-SOIC (Surface Mount) | 28-SSOP (Surface Mount) | Different package footprints (SOIC vs SSOP) require different PCB land patterns, so they are not drop-in board replacements. |
| Packaging / Delivery Form | Tube | Tape & Reel | Different packaging forms affect assembly line handling and inventory; the reel version suits automated pick-and-place production. |

Frequently asked questions
What are the key differences between the AD9220AR and AD9220ARS-REEL?
Both parts are the same AD9220 12-bit, 10 MSPS analog-to-digital converter from Analog Devices. The AD9220AR is supplied in a 28-lead SOIC package in tube form, while the AD9220ARS-REEL is the same die in a 28-lead SSOP package supplied on tape and reel for automated assembly. The core electrical specifications are identical; the differences are package type and shipping format.
Are the AD9220AR and AD9220ARS-REEL electrically interchangeable?
Yes, both variants share the same AD9220 silicon and datasheet specifications, including 12-bit resolution, 10 MSPS maximum sampling rate, and the same analog input and digital output characteristics. However, because the packages differ (SOIC vs SSOP), the PCB footprint and land pattern are not interchangeable, so a board redesign is required to substitute one for the other.
What package types do the AD9220AR and AD9220ARS-REEL use?
The AD9220AR is offered in a 28-lead SOIC (wide body) package. The AD9220ARS-REEL is offered in a 28-lead SSOP package. Both are surface-mount packages, but their body dimensions, lead pitch, and land patterns differ, so they cannot be mounted on the same PCB footprint.
Why is the AD9220ARS-REEL supplied on tape and reel?
The "-REEL" suffix indicates the AD9220ARS is packaged on tape and reel, which is the standard format for high-volume automated pick-and-place assembly lines. The AD9220AR in tube form is typically used for prototyping, low-volume runs, or manual assembly. The electrical performance of the device is unaffected by the shipping format.
Do the AD9220AR and AD9220ARS-REEL have the same operating temperature range?
Yes. Both the AD9220AR and AD9220ARS-REEL are specified over the industrial temperature range of -40°C to +85°C, consistent with the AD9220 datasheet. Package type and shipping format do not change the rated temperature range.
Can the AD9220ARS-REEL be used as a drop-in replacement for the AD9220AR?
No, not as a drop-in replacement. Although the electrical function is identical, the AD9220ARS-REEL uses a 28-lead SSOP package while the AD9220AR uses a 28-lead SOIC package. The different footprints require a PCB layout change before substitution. Electrical compatibility should still be confirmed against the AD9220 datasheet for the target design.
Which variant should be selected for production versus prototyping?
For high-volume automated production, the AD9220ARS-REEL is generally preferred because tape-and-reel packaging supports pick-and-place assembly. For prototyping, evaluation, or low-volume builds, the AD9220AR in tube packaging is often more convenient. Selection should also account for the PCB footprint required by each package.
