AD875-EB - 10-Bit, 15 MHz CMOS ADC Evaluation Board | Analog Devices
N.º da peça: AD875-EB ✗ Fim de vidaAD875-EB Visão geral
An ADC converts an analog input voltage into a digital number for processing, storage, measurement, or control. The AD875 belongs to the ADC and DAC hierarchy within integrated circuits and is positioned as a low-power, high-speed sampling converter. Its 10-bit resolution provides 1,024 digital codes, while the 15 MHz sampling rate makes it applicable to waveform capture, communications, instrumentation, and industrial control systems requiring substantially faster conversion than conventional slow-rate ADCs.
The AD875 supports straight binary and two's-complement output formats, providing flexibility when interfacing with digital processing hardware. Dedicated underrange and overrange output bits indicate when the analog input lies outside the converter's useful conversion range, allowing a system to detect overload or underscale conditions. These interface features make the evaluation board useful for evaluating digital output behavior, logic compatibility, standby performance, and system-level timing.
The verified AD875 data sheet states that the converter operates from a single supply and combines 10-bit resolution, 15 MHz performance, and low power consumption. The evaluation board is intended to provide a platform for assessing these characteristics with the AD875 device. Its exact board dimensions, connector details, component population, schematic, and supported access modes are not included in the verified search results and therefore require confirmation from the original board documentation.
AD875-EB is best used when engineers need to characterize a 10-bit CMOS ADC rather than a complete finished instrument. Typical evaluation work includes measuring conversion timing, checking output coding, verifying +3.3 V or +5 V digital-interface compatibility, observing standby current, and assessing underrange and overrange behavior with external test equipment.
Designers should avoid assuming that the AD875-EB board and the AD875 IC are electrically interchangeable. The former is an evaluation platform, while the latter is the converter being evaluated. Before schematic capture or PCB reuse, obtain the board guide and verify supply polarity, analog input range, digital interface voltage, clock arrangement, connector orientation, and the populated versus bare-board configuration.
This page consolidates the verified AD875 converter capabilities, procurement links, evaluation-board identification, and engineering cautions that are often scattered across distributor records and general search results. It also separates documented facts from missing board-level information, helping teams decide when additional manufacturer documentation is required before lab use or design conversion.

Aplicações típicas
AD875-EB é adequado para 6 aplicaçãos: ADC Waveform Characterization, Communications Front-End Development, Industrial Measurement Prototype, Low-Power Duty-Cycled Sampling, Digital Interface Compatibility Testing, Instrumentation Signal-Chain Evaluation.
ADC Waveform Characterization
The AD875-EB is appropriate for laboratory evaluation of a 10-bit, 15 MHz CMOS ADC when the goal is to observe sampled waveforms and confirm output behavior. According to the verified AD875 data sheet, the converter supports straight binary and two's-complement formats, giving engineers two ways to interpret the same conversion data. The evaluation-board form permits connection to external clock, analog stimulus, and digital capture equipment without requiring an initial production PCB. Designers should verify the board's input range, clock arrangement, and connector map before applying signals, because those details are not present in the supplied search results.
Recomendado
Communications Front-End Development
AD875-EB can support early development of a communications signal chain requiring 10-bit conversion at 15 MHz. The verified converter specifications identify CMOS technology, 185 mW operating power, and digital I/O compatibility with either +3.3 V or +5 V logic, which are useful attributes when interfacing a converter prototype with communications hardware. Straight binary and two's-complement outputs provide flexibility for system-level coding tests, while underrange and overrange bits can help identify invalid input conditions. Final signal-integrity conclusions require the missing input-range, SNR, INL, DNL, and clock-jitter data.
Recomendado
Industrial Measurement Prototype
The AD875-EB provides a practical platform for prototyping industrial measurement and control functions around a 10-bit ADC. Its 15 MHz sampling rate is substantially higher than many low-rate instrumentation ADCs, while the documented standby mode can reduce power below 50 mW for duty-cycled acquisition. The 185 mW operating-power figure helps engineers estimate thermal and supply requirements at the converter level. Because no industrial temperature grade, isolation rating, EMC qualification, or accuracy limits are supplied for the board, production suitability must not be inferred from prototype performance alone.
Recomendado
Low-Power Duty-Cycled Sampling
AD875-EB is useful when evaluating whether an ADC design can exploit standby operation rather than remain in continuous conversion. The verified AD875 information states 185 mW normal power and less than 50 mW in standby, providing a concrete basis for comparing operating states. Engineers can control external power and timing to observe transition behavior and calculate a duty-cycle energy budget. The actual average power depends on board overhead, clocking, interface activity, and supply architecture, none of which are quantified in the supplied sources, so measurements should separate converter performance from evaluation-board consumption.
Recomendado
Digital Interface Compatibility Testing
The AD875-EB can support interface experiments involving +3.3 V and +5 V digital logic levels, two output codings, and a high-impedance output state. These features make it relevant to controllers, FPGAs, DSPs, and data-capture equipment that need to confirm output timing and level compatibility. The verified source confirms that the converter's digital I/O can operate with either +5 V or +3.3 V logic and that outputs can enter a high-impedance state. Before connecting equipment, confirm the populated board's level configuration and do not infer connector voltage from the converter capability alone.
Recomendado
Instrumentation Signal-Chain Evaluation
AD875-EB supports bench evaluation of an instrumentation signal chain in which a fast 10-bit ADC is operated with controlled analog and digital test equipment. Its 15 MHz conversion capability can help characterize acquisition timing, output coding, and range detection rather than serving as a finished high-accuracy measurement instrument. Dedicated underrange and overrange outputs provide useful diagnostics when the input is outside the expected range. The supplied sources omit SNR, INL, DNL, input impedance, and analog input range, all of which are critical for metrology work and must be obtained before interpreting results as instrument-grade accuracy.

Notas de projeto
Separate converter power from board-level consumption during characterization. The verified AD875 data identifies 185 mW normal operating power and standby power below 50 mW, but it does not specify the associated supply voltage or the evaluation board's regulator efficiency. Measure current at the board input while cycling conversion, clock, and digital-output activity. Record the exact supply voltage, operating state, and test duration so the resulting average-power calculation can be reproduced.
Use a controlled clock and clean analog stimulus when evaluating the 15 MHz conversion path, because timing jitter, source impedance, and ground return paths can affect apparent converter performance. Confirm the AD875-EB input range, recommended source impedance, and clock layout from the missing schematic and user guide. The supplied data confirms 10-bit resolution and range-indicator outputs, but it does not provide SNR, INL, DNL, input impedance, or timing specifications needed to set an appropriate test plan.
Do not substitute the AD875-EB board pinout for the AD875 IC pinout without checking the board schematic. The verified sources describe converter-level functions, including +3.3 V or +5 V digital I/O, standby, output coding, and underrange or overrange bits, but they do not identify the evaluation board's connectors. Obtain the board guide, schematic, and component population list before wiring instrumentation, power, or a digital processor. Verify supply polarity and logic levels at the connector rather than relying only on the converter data sheet.
Keep analog stimulus, converter supply, and digital capture paths physically separated while evaluating the board. Use a low-noise ground reference and short return paths, and avoid routing test clocks parallel to sensitive input connections. If the board can be populated or modified, document every jumper, termination, and populated component because evaluation hardware can differ between revisions. Preserve the original configuration when recording results so measurements remain repeatable and attributable to a specific board configuration.
