AD9280ARSZRL - 8-Bit 32 MSPS ADC | Analog Devices
MPN： AD9280ARSZRL ✓ 啟用中AD9280ARSZRL 概覽
An ADC is a data-conversion IC that samples an analog voltage and converts it into a digital code. Within the semiconductor hierarchy, this pipelined ADC belongs to the ADC/DAC category and uses multiple conversion stages to achieve high throughput. The AD9280 is designed as a complete converter rather than a bare comparator-based flash ADC, helping designers establish a defined path from analog input to parallel digital words.
Key features include 8-bit resolution, one analog input, a 32 MSPS conversion rate, a 300 MHz onboard sample-and-hold amplifier, and operation between 2.7 V and 5.5 V. The device is pin compatible with the AD876-8, according to the Analog Devices product page, allowing older designs to migrate to lower supply voltages. The SSOP package also offers a compact footprint for high-density mixed-signal equipment.
Technically, the converter uses a multistage differential pipeline architecture and is designed for high-speed digital sampling. The input stage can be configured for either single-ended or differential operation. Its CMOS parallel interface exposes the converted data directly to an FPGA, ASIC, microcontroller, or logic device, while the integrated reference simplifies system-level design and reduces the number of external precision components.
Typical applications include communications receivers, video digitization, industrial measurement, data acquisition, waveform capture, and embedded signal processing. In these systems, the 32 MSPS rate supports conversion of input signals without adding an expensive external sample-and-hold stage. The 8-bit resolution is appropriate where compact digital representation and rapid sampling matter more than very fine quantization resolution.
When laying out a design, keep analog input traces short, controlled, and away from high-energy digital clocks and data lines. Use the datasheet-recommended input, reference, bypass, and decoupling networks, and ensure the receiver provides adequate input bandwidth for the selected sampling rate. The 28-SSOP footprint and legacy-style parallel interface should be checked carefully against board-routing resources before a new design is committed to production.
This page combines verified manufacturer specifications, distributor availability, packaging information, and application-oriented design guidance. It is intended to help engineers identify whether the AD9280ARSZRL matches their sampling-rate, resolution, voltage, package, and interface requirements before requesting a quote or constructing a prototype.

典型應用
AD9280ARSZRL 適用於 6 應用s: Communications Signal Acquisition, Video Digitization, Industrial Data Acquisition, Waveform Capture, RF and IF Monitoring, Embedded Test and Measurement.
Communications Signal Acquisition
The AD9280ARSZRL fits communications front ends that need rapid conversion into a parallel digital stream. Its 32 MSPS sampling rate and 8-bit resolution provide a compact digitizer for receiver monitoring, IF or baseband processing, and embedded communications equipment. The onboard sample-and-hold amplifier and integrated reference reduce analog support complexity. In implementation, place the ADC close to the source or filter, keep the clock path short, and verify that downstream logic can accept the converter's CMOS data at the selected sampling rate.
推薦
Video Digitization
The AD9280ARSZRL is suitable for digitizing video or composite-related analog signals when 8-bit parallel data and a 32 MSPS sampling rate are sufficient. Its onboard sample-and-hold amplifier accepts the input stage before the pipelined conversion process, while the CMOS output can feed an FPGA or video ASIC. The system should include source termination or gain control, an appropriate anti-alias filter, and controlled grounding. Verify bandwidth, settling behavior, and clock jitter against the target video bandwidth before using the ADC as a drop-in subsystem element.
推薦
Industrial Data Acquisition
For industrial measurement and control systems, the AD9280ARSZRL provides a compact 32 MSPS conversion path for rapidly varying sensor or conditioned process signals. The 8-bit resolution is useful for supervisory measurements, waveform capture, and feedback loops where quantization and throughput are acceptable. Use the integrated sample-and-hold amplifier to reduce external analog switching complexity, and isolate the analog input from digital clocks and switching regulators. The converter's parallel interface requires careful bus routing and an appropriate FPGA or controller termination strategy.
推薦
Waveform Capture
The AD9280ARSZRL can serve as the acquisition engine in a compact waveform-capture instrument when an 8-bit, 32 MSPS stream is adequate. The onboard sample-and-hold amplifier captures the conditioned input, and the integrated reference supports a self-contained converter block. The capture system should provide anti-alias filtering, a low-jitter sampling clock, sufficient analog gain, and a buffer or FPGA capable of storing the parallel output. Trigger timing and memory bandwidth often determine whether the full sample rate is practical in the finished instrument.
推薦
RF and IF Monitoring
The AD9280ARSZRL can be used in RF or intermediate-frequency monitoring paths where the system needs to translate a conditioned analog observation into an 8-bit digital measurement. The 32 MSPS rate supports high-speed envelope or waveform observation, while the onboard sample-and-hold amplifier simplifies the input stage. RF designers should still account for mixer or detector bandwidth, aliasing, gain distribution, and clock jitter. The CMOS output is particularly convenient for FPGA-based demodulation, calibration, or digital filtering.
推薦
Embedded Test and Measurement
The AD9280ARSZRL is appropriate for embedded measurement subsystems that need more sampling throughput than a general-purpose ADC can provide. Its 28-lead SSOP package and integrated reference help create a compact converter section, while the parallel CMOS output connects naturally to FPGA logic or a processor bus interface. The designer should verify pin assignment, clock polarity, output timing, and input voltage range against the datasheet. Mechanical spacing and analog isolation are especially important when the ADC is mounted close to a switching power supply.

主要差異化特點
- Verified conversion throughput (對比AD9280ARSZ)
- Integrated converter front end (對比AD876-8)
- Migration-compatible architecture (對比AD876-8)
- Single-ended or differential input flexibility (對比AD9283BRS-RL80)
設計說明
Place the AD9280ARSZRL close to the signal source and place its decoupling components near the supply pins. Keep analog input routing short and separate from parallel data outputs and clock lines. Use a continuous ground reference and minimize loop area around the analog front end. The converter's 32 MSPS capability can be limited by board-level trace impedance, return-current paths, and coupling even when the IC itself meets its specified rate.
Treat the eight-bit parallel output as a synchronous digital bus. Route the data lines together to minimize skew, terminate them appropriately according to the clock and logic family, and confirm receiver thresholds against the CMOS output timing. Provide a low-jitter sampling clock and keep the clock trace away from analog input routing. Validate timing with the complete source, package, PCB, and receiving-device load rather than relying only on the datasheet's isolated timing figures.
Do not substitute an AD876-8 or another related ADC solely from a pin-compatibility statement. Confirm resolution, maximum sampling rate, supply range, input range, reference behavior, output coding, clock polarity, timing, and package footprint. Likewise, distinguish ordering suffixes such as AD9280ARSZ, AD9280ARSRL, AD9280ARS, and AD9280ARSZRL before procurement. For production, use the manufacturer datasheet ordering table and distributor stock linked to the exact suffix.
The verified distributor information lists 80 mW power dissipation at a 3 V supply for the AD9280ARSZRL. Actual board power depends on the operating voltage, sampling activity, output loading, and adjacent circuitry. Use stable supply rails, local bypass capacitors, and a power source with adequate transient response for the parallel output. Confirm the datasheet's recommended capacitor values and voltage tolerances rather than estimating values from the nominal operating range.
合規資訊
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because AD9280ARSZRL is an ADC rather than an automotive-qualified power device; the supplied data does not state an automotive qualification claim.
