Replacement verdict
Compatible functional replacement candidate
The AD9220AR and AD9220AR-REEL are functionally identical 12-bit, 10 MSPS analog-to-digital converters from Analog Devices, differing only in packaging format. The AD9220AR is supplied in tube packaging, while the AD9220AR-REEL is supplied on tape and reel for automated assembly. Both share the same die, electrical specifications, and 28-lead SOIC footprint, making them fully interchangeable for design and production purposes.

Key electrical and mechanical differences between the two devices
| Parameter | AD9220AR | AD9220AR-REEL | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Determines the quantization precision of the ADC; both parts provide identical 12-bit output, so conversion accuracy is the same. |
| Sampling Rate | 10 MSPS | 10 MSPS | Sets the maximum input signal bandwidth the ADC can digitize; identical rates mean the same throughput capability. |
| Number of Inputs / Channels | 1 (single-ended) | 1 (single-ended) | Defines how many analog signals can be converted; both are single-channel, so system architecture compatibility is unchanged. |
| Input Type | Single-ended | Single-ended | Affects the analog front-end design; identical input configuration allows the same driver circuitry to be reused. |
| Supply Voltage | 5 V (analog and digital) | 5 V (analog and digital) | Determines power rail requirements; matching supplies mean no redesign of the power subsystem is needed. |
| Package / Case | 28-SOIC | 28-SOIC | Defines the PCB footprint and assembly process; identical packages allow drop-in board compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Specifies the environmental envelope for reliable operation; matching ranges ensure the same application conditions apply. |
| Packaging / Delivery Form | Tube / individual | Tape & Reel | Affects manufacturing handling and automated pick-and-place assembly; the reel version suits high-volume SMT lines while the tube version suits low-volume or prototyping. |
| Interface / Output Format | Parallel CMOS | Parallel CMOS | Determines how the digital output connects to the host processor or FPGA; identical interfaces allow the same digital backend to be used. |

Frequently asked questions
What is the difference between AD9220AR and AD9220AR-REEL?
The AD9220AR and AD9220AR-REEL refer to the same AD9220 12-bit, 10 MSPS analog-to-digital converter in a 28-lead SOIC package. The "-REEL" suffix denotes a tape-and-reel packaging option for automated assembly, while the base AD9220AR designation refers to the same device supplied in standard packaging. Electrical performance and die are identical.
Are the AD9220AR and AD9220AR-REEL electrically and functionally identical?
Yes. Both part numbers correspond to the same AD9220 converter die and specification. The only documented difference is the shipping/packaging format (tape-and-reel versus standard), so AC and DC performance, pinout, and operating conditions are the same.
What are the key specifications of the AD9220?
The AD9220 is a 12-bit monolithic A/D converter with a maximum sampling rate of 10 MSPS. It operates from a single +5 V supply, features an on-chip sample-and-hold amplifier and reference, and provides a parallel 12-bit output. It is specified for operation over the industrial temperature range and is available in a 28-lead SOIC package.
Can AD9220AR and AD9220AR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they are the same device in the same 28-lead SOIC package. The choice between them is driven by assembly and inventory considerations (tape-and-reel for automated pick-and-place versus standard packaging), not by functional differences.
Why would a designer choose the AD9220AR-REEL version?
The AD9220AR-REEL is supplied in tape-and-reel format, which is suited to high-volume automated surface-mount assembly lines. It allows pick-and-place equipment to feed the 28-lead SOIC devices efficiently, reducing manual handling compared with standard packaging.
Do AD9220AR and AD9220AR-REEL share the same package and pinout?
Yes. Both are offered in the 28-lead SOIC (R-28) package with the same pin assignments. Because the package and pinout are identical, the PCB land pattern and layout are the same for both part numbers.
What supply voltage and sampling rate does the AD9220 support?
The AD9220 operates from a single +5 V analog supply and supports a maximum sampling rate of 10 MSPS with 12-bit resolution. These parameters apply equally to the AD9220AR and AD9220AR-REEL since they are the same device.
