Replacement verdict
Compatible functional replacement candidate
The AD9280ARSRL is a tape-and-reel packaged variant of the AD9280ARS and is functionally interchangeable with it. Both parts share the same 8-bit ADC architecture, 32 MSPS sampling rate, analog input range, supply requirements, and 28-lead SSOP footprint, so the AD9280ARSRL can serve as a direct functional replacement in existing designs. The only meaningful distinction is the packaging format, which affects inventory handling and automated assembly rather than electrical performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD9280ARS | AD9280ARSRL | Why it matters |
|---|---|---|---|
| Resolution | 8 bits | 8 bits | Determines the quantization precision of the ADC; both parts must match for identical digital output behavior. |
| Sampling Rate | 32 MSPS | 32 MSPS | Sets the maximum conversion throughput; identical rates ensure the same signal bandwidth handling. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Defines the operating power rail range; matching ranges allow drop-in replacement in the same circuit. |
| Analog Input Type | Single-ended | Single-ended | Determines the input signal conditioning required; identical input topology preserves the analog front-end design. |
| Package / Case | 28-SSOP | 28-SSOP | Footprint and pinout must match for physical board compatibility and reflow assembly. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device meets the environmental requirements of the target application. |
| Power Consumption | ~95 mW typical | ~95 mW typical | Affects thermal budget and power supply sizing; identical consumption keeps system power design unchanged. |
| Packaging / Ordering Format | Tube / individual | Tape and reel | The RL suffix denotes tape-and-reel packaging for automated assembly; the electrical part is the same but the delivery format differs. |

Frequently asked questions
What is the difference between AD9280ARS and AD9280ARSRL?
The AD9280ARS and AD9280ARSRL are the same Analog Devices 8-bit, 32 MSPS analog-to-digital converter in a 28-lead SSOP package. The difference is packaging format: AD9280ARS is supplied in tube/tray quantities, while the "RL" suffix denotes tape-and-reel packaging for automated assembly. Electrical and functional specifications are identical.
Are AD9280ARS and AD9280ARSRL electrically and functionally interchangeable?
Yes. Both orderable part numbers share the same die, package (28-lead SSOP), pinout, and datasheet specifications, including 8-bit resolution, 32 MSPS maximum sampling rate, and 2.7 V to 5.5 V supply range. They differ only in shipping media, so they are interchangeable in a validated design.
What are the key specifications of the AD9280?
The AD9280 is an 8-bit monolithic sampling ADC with a maximum conversion rate of 32 MSPS, on-chip sample-and-hold amplifier, and internal voltage reference. It operates from a single 2.7 V to 5.5 V supply, offers a 300 MHz analog input bandwidth, and provides a power-down mode. It is specified for operation over the industrial temperature range of −40°C to +85°C.
What package do AD9280ARS and AD9280ARSRL use?
Both parts are offered in a 28-lead Shrink Small Outline Package (SSOP). The package and pinout are identical between the two orderable codes, so PCB land patterns and footprint designs are the same.
Why would a design choose the AD9280ARSRL tape-and-reel version over AD9280ARS?
The AD9280ARSRL is supplied on tape and reel, which is compatible with automated pick-and-place assembly lines and high-volume production. The AD9280ARS tube/tray format is typically used for prototyping, low-volume runs, or manual assembly. Selection depends on manufacturing method, not on device performance.
Can AD9280ARS and AD9280ARSRL be mixed on the same PCB assembly?
Yes. Because both orderable part numbers are the same device in the same 28-lead SSOP package with identical pinout and specifications, they can be used interchangeably on the same board without design changes, provided each is handled according to its shipping format.
What supply voltage and sampling rate do AD9280ARS and AD9280ARSRL support?
Both devices operate from a single supply of 2.7 V to 5.5 V and support a maximum sampling rate of 32 MSPS, with an 8-bit resolution and an on-chip sample-and-hold amplifier, per the Analog Devices AD9280 datasheet.
