Replacement verdict
Compatible functional replacement candidate
The AD9280ARSZ and AD9280ARSZRL are functionally identical 8-bit, 32 MSPS analog-to-digital converters from Analog Devices, differing only in packaging format (tube vs. tape-and-reel). Both share the same die, SSOP-28 package, supply and reference requirements, and temperature range, making the reel variant a direct drop-in substitute for the tube variant in automated assembly flows.

Key electrical and mechanical differences between the two devices
| Parameter | AD9280ARSZ | AD9280ARSZRL | Why it matters |
|---|---|---|---|
| Resolution | 8 bit | 8 bit | Determines the quantization precision of the ADC; both parts provide identical 8-bit conversion, so no change in system accuracy. |
| Sampling Rate | 32 MSPS | 32 MSPS | Sets the maximum input signal bandwidth the ADC can digitize; identical rates mean the same analog front-end bandwidth is supported. |
| Number of Input Channels | 1 | 1 | Defines how many analog signals can be sampled; both are single-channel, so board-level channel architecture is unchanged. |
| Input Type | Single-ended | Single-ended | Affects how the analog source must be driven and referenced; identical input topology allows the same driver circuit to be reused. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Determines power rail compatibility; identical ranges mean the same supply design works for either part. |
| Package / Case | 28-SSOP | 28-SSOP | Footprint and thermal characteristics must match for drop-in substitution; identical packages ensure PCB compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental envelope for reliable operation; identical ranges mean the same application conditions apply. |
| Packaging / Reel | Tube | Tape & Reel | Affects manufacturing handling and pick-and-place assembly; the RL variant is reeled for automated production while the base part is tube-packed. |
| Moisture Sensitivity Level (MSL) | MSL 1 (Unlimited) | MSL 1 (Unlimited) | Indicates floor-life and baking requirements before reflow; both share the same MSL, so handling procedures are identical. |

Frequently asked questions
What is the difference between AD9280ARSZ and AD9280ARSZRL?
Both are the same Analog Devices AD9280 8-bit, 32 MSPS analog-to-digital converter in a 28-lead SSOP package. The difference is packaging format: AD9280ARSZ is supplied in tube/tray quantities, while AD9280ARSZRL is the tape-and-reel version intended for automated pick-and-place assembly. Electrical and functional specifications are identical.
Are AD9280ARSZ and AD9280ARSZRL electrically and functionally interchangeable?
Yes. Both ordering codes refer to the same silicon device, the AD9280, with identical resolution (8-bit), sampling rate (32 MSPS), analog input range, supply requirements, and pinout. The suffix difference reflects only the shipping/packaging format, so they are interchangeable in a design.
What are the key specifications of the AD9280?
The AD9280 is an 8-bit monolithic analog-to-digital converter with a maximum sampling rate of 32 MSPS. It operates from a single 2.7 V to 5.5 V supply, features an on-chip sample-and-hold amplifier, and provides a flexible analog input range. It is specified for operation over the industrial temperature range and is available in a 28-lead SSOP package.
Which package do AD9280ARSZ and AD9280ARSZRL use?
Both parts are offered in the 28-lead Shrink Small Outline Package (SSOP), designated by the "RS" code in the ordering part number. The package, pinout, and PCB land pattern are identical for both ordering codes.
Why would a design choose the AD9280ARSZRL tape-and-reel version over the AD9280ARSZ?
The AD9280ARSZRL tape-and-reel format is suited to high-volume automated surface-mount assembly, where reels feed pick-and-place equipment efficiently. The AD9280ARSZ tube/tray format is typically used for prototyping, low-volume runs, or manual assembly. The choice is purely a manufacturing/logistics decision, not a performance one.
Can AD9280ARSZ and AD9280ARSZRL be mixed on the same PCB assembly?
Yes. Because both ordering codes describe the same device with identical package, pinout, and electrical characteristics, either can be placed on the same board without design changes. Mixing is acceptable as long as inventory and traceability requirements are met.
Do AD9280ARSZ and AD9280ARSZRL differ in temperature range or qualification?
No. Both ordering codes refer to the same AD9280 device grade and are specified over the same operating temperature range defined in the Analog Devices datasheet. Packaging format does not affect temperature rating or qualification status.
