AD871-EB - 12-Bit 5 MSPS ADC Evaluation Board | Analog Devices
부품 번호: AD871-EB ✓ 활성AD871-EB 개요
An ADC is an analog-to-digital converter, a semiconductor that converts continuously varying analog voltages into digital codes for processing, storage, display, or control. The AD871 belongs to the converter hierarchy that includes ADC, data converter, mixed-signal IC, and semiconductor. A 12-bit converter provides 4,096 possible digital code levels, while its 5 MSPS conversion rate permits up to five million samples per second when operated within specified timing and input conditions.
The verified AD871 features include monolithic 12-bit, 5 MSPS conversion, a low-noise input track-and-hold amplifier, and an on-chip voltage reference. Published feature data also identifies 0.17 LSB RMS input-referred noise, guaranteed differential nonlinearity of 0.5 LSB, 68 dB signal-to-noise and distortion ratio, and 73 dB spurious-free dynamic range. These characteristics make the converter platform relevant to precision imaging, instrumentation, and signal-processing systems where quantization error and harmonic performance matter.
The AD871 uses a high-performance sampling architecture to capture an analog input before conversion. Its integrated voltage reference reduces the need for an external reference in suitable designs, while the track-and-hold amplifier isolates the source during the acquisition interval. The verified manufacturer information states that the AD871 is pin compatible with the AD872, allowing system requirements to change without relocating the converter footprint.
The AD871-EB is intended for evaluating the underlying converter behavior and supporting system development. Typical evaluation activities include input-range verification, digital-output inspection, noise characterization, differential-nonlinearity testing, and signal-to-noise measurement. The same converter characteristics make the platform relevant to high-end imaging, industrial vision, laboratory instrumentation, and embedded acquisition systems, subject to the AD871 operating limits.
Design evaluation should begin with the manufacturer datasheet and the board documentation rather than assumptions based only on the converter headline specifications. Verify the exact board wiring, supported input ranges, digital-interface arrangement, clock requirements, reference configuration, and test-point assignments before prototyping. This page separates verified AD871-EB and AD871 information from unspecified board-level data so that missing electrical and mechanical details are not presented as established facts.
This page consolidates verified manufacturer descriptions, distributor status, practical evaluation guidance, and explicit data-gap markers. That combination gives engineers a more useful starting point for understanding the AD871-EB while identifying which board-specific details still require confirmation from official documentation.

High-End Imaging Evaluation
The AD871-EB is appropriate for evaluating the AD871 in high-end imaging systems because Analog Devices specifically describes the converter's low-noise input track-and-hold amplifier as ideally suited to imaging. The verified 0.17 LSB RMS input-referred noise, 68 dB SNR and distortion, and 73 dB spurious-free dynamic range provide useful baselines for comparing optical or sensor-interface designs. Engineers can use the platform to observe sampling behavior and digital-code stability before committing to a compact production layout. Because no schematic, connector map, or input-range table appears in the supplied records, signal conditioning, synchronization, and probing arrangements must be confirmed from the official board documentation rather than inferred from the converter specifications alone.
추천
Laboratory Signal Acquisition
For laboratory signal acquisition, the AD871-EB provides a platform for evaluating a 12-bit converter that can sample at 5 MSPS. The integrated track-and-hold amplifier and on-chip voltage reference reduce the number of external elements that must be characterized before a system design is finalized. Verified performance figures including 0.17 LSB RMS noise and guaranteed differential nonlinearity of 0.5 LSB can serve as acceptance baselines for fixture and instrument development. The supplied records do not identify analog bandwidth, settling time, acquisition timing, or board power rails, so laboratory users should establish those limits from the manufacturer datasheet and avoid using the 5 MSPS headline rate as a substitute for full dynamic specifications.
추천
Industrial Vision Development
The AD871-EB is useful during industrial vision development where sensor waveforms must be converted before feature extraction or inspection decisions are made. Its 12-bit resolution provides 4,096 code levels, while the 5 MSPS conversion rate supports sampling of suitable visual or sensor signals. The verified 73 dB spurious-free dynamic range can help engineers compare signal-chain revisions and identify harmonic distortion introduced by excitation, analog conditioning, or board layout. For a production camera or inspection system, engineers should separately evaluate sensor drive bandwidth, synchronization jitter, analog input range, and connector assignment because these board-specific details are not present in the supplied AD871-EB records and must be verified before production migration.
추천
Precision Instrumentation
The AD871-EB can support evaluation of precision instrumentation front ends that require more than eight-bit quantization but do not require the highest conversion rates. The AD871's 12-bit resolution, 5 MSPS capability, and 68 dB SNR and distortion provide a defined starting point for measuring the influence of source impedance, analog filtering, grounding, and sampling-clock quality. Its guaranteed 0.5 LSB differential nonlinearity is also relevant when checking monotonic behavior in a measurement chain. However, the evaluation board should not be treated as a complete instrument front end: the supplied sources do not specify input-range scaling, reference behavior, clock input, digital output interface, or analog bandwidth. These details require confirmation before interpreting laboratory measurements or designing the production analog interface.
추천
Data-Acquisition Prototype
AD871-EB is suitable for prototyping the data-acquisition stage of a mixed-signal system because it exposes a known evaluation platform around the AD871 rather than requiring immediate bare-IC assembly. The 5 MSPS sampling capability can support acquisition of waveforms whose bandwidth is appropriately limited, while 12-bit resolution provides a practical balance between data rate and conversion resolution. During prototyping, engineers should compare digital outputs across input levels and frequencies, monitor code transitions for missing outputs, and assess noise under realistic loading. The exact board output interface and test points are not identified in the supplied data, so the official schematic and user documentation should be consulted before configuring a host controller or automated measurement fixture.
추천
ADC Characterization Training
The AD871-EB is useful as an educational platform for engineers who need to characterize quantization, differential nonlinearity, noise, and dynamic performance in a practical converter system. The published 0.5 LSB differential-nonlinearity guarantee, no-missing-codes guarantee, 68 dB SNR and distortion, and 73 dB SFDR provide concrete reference points for laboratory exercises. A training setup can compare input excitation levels, grounding arrangements, clock sources, and output decoding while learning how analog and digital implementation choices affect measurements. Because the verified data does not expose the board's connectors, supply voltages, test points, or control signals, all fixture wiring should be established from the official AD871-EB documentation and the converter datasheet rather than inferred from the ADC headline specifications.

설계 노트
Do not treat the AD871's bare-converter pinout as the AD871-EB board pinout. The verified evidence establishes pin compatibility between the AD871 and AD872 converter ICs, but it does not provide a connector-level map for the evaluation platform. Identify the board revision and consult the official schematic, user guide, and test-point documentation before attaching signal sources, clocks, power supplies, or digital acquisition equipment.
Evaluate noise, differential nonlinearity, and spurious-free dynamic range only under a documented source, clock, grounding, and loading configuration. The verified converter baselines are 0.17 LSB RMS input-referred noise, 0.5 LSB guaranteed differential nonlinearity, 68 dB SNR and distortion, and 73 dB SFDR, but these values do not characterize every possible board implementation. Preserve the manufacturer-recommended input and reference arrangements and record test conditions so board-level results can be compared meaningfully.
Confirm the AD871-EB supply voltages and grounding arrangement from official board documentation before power-up. The supplied web data verifies the AD871 converter's on-chip voltage reference and track-and-hold amplifier but does not identify the evaluation board's external supply rails, input range, or power consumption. Avoid inferring those values from the converter alone, and use adequately decoupled, low-noise sources where the manufacturer evaluation setup specifies them.
