AD4030-24FMCZ - 24-Bit 2 MSPS SAR ADC Evaluation Board | Analog Devices
MPN： AD4030-24FMCZ ✓ 啟用中AD4030-24FMCZ 概覽
An evaluation board is a dedicated PCB that engineers use to characterize a complex component without first committing to a custom design. The AD4030-24FMCZ pairs the AD4030-24 single-channel 24-bit SAR ADC with a configurable analog front end (AFE), enabling engineers to evaluate noise, linearity, and throughput against datasheet limits. ADCs of this precision category are typically used as precision data acquisition front-ends and as benchmark modules when prototyping measurement systems.
Key features highlighted by the manufacturer include a guaranteed maximum ±0.9 ppm integral nonlinearity (INL), no missing codes at 24 bits across the -40 °C to +125 °C operating range, a 2 MSPS sample rate (the related AD4032-24 is the 500 kSPS variant), and the Easy Drive input architecture that simplifies the drive amplifier chain. The on-chip reference buffer with integrated decoupling capacitor reduces external BOM count, and the no-pipeline-delay track-and-hold makes the part suitable for multiplexed control loops.
The board uses Analog Devices' Flexi-SPI interface, supporting standard SPI, echo-clock, and ADC-host-clock modes plus optional DDR clocking. This allows 10 MHz serial clock operation while sustaining 2 MSPS conversion throughput, easing FPGA timing closure and enabling galvanic isolation with standard digital isolators. Power-on-reset (POR) on both 5 V and 1.8 V rails resets internal registers at power-up and on rail collapse.
Typical applications include precision industrial weighing scales, seismic and geophysical instrumentation, medical patient-monitoring front-ends, multi-channel data-acquisition modules, and audio-bandwidth high-resolution measurement systems. The wide common-mode input range of the Easy Drive inputs lets the board digitize signals directly from bridges, thermocouples, and current-sense shunts. The no-latency track-and-hold also suits closed-loop control systems where deterministic acquisition timing is essential.
The most common design trade-off for engineers using this eval board is FMC connector routing - long impedance-discontinued traces will degrade the 2 MSPS / 24-bit noise floor. Use the shortest possible cable to the host, and where possible capture full-resolution samples into the FPGA fabric before any rate compression. For noisy bench environments, power the board through a linear supply rather than the FMC 5 V rail.

Precision Weighing Scales
The AD4030-24's ±0.9 ppm maximum INL and no-missing-codes 24-bit performance make the EVAL-AD4030-24FMCZ an ideal board for evaluating front-end signal chains for industrial weighing scales. The Easy Drive analog front end accepts the high-impedance output of a load-cell bridge directly, while the 2 MSPS throughput lets designers oversample and digitally average at 24 bits of resolution. The 5 V / 1.8 V POR guarantees deterministic boot of the load-cell calibration sequence after power-up. Placed between the load cell output and a ZedBoard controller, the board demonstrates a complete weigh-scale prototype with proper grounding and shielding — ensuring accuracy well below the 6000e commercial scale specification.

Seismic and Geophysical Instrumentation
The AD4030-24's 24-bit dynamic range and 2 MSPS sample rate suit broadband seismic and geophysical instrumentation where wide-bandwidth high-resolution digitisation of piezo and geophone signals is required. According to the AD4030-24/AD4032-24 datasheet, the SAR converter's zero pipeline delay is critical when synchronising to GPS timing pulses in field acquisition units. The Flexi-SPI interface with echo-clock and DDR options keeps serial clock rates low, simplifying the use of digital isolators in the field station wiring. The EVAL-AD4030-24FMCZ lets engineers qualify the ADC noise floor against geophone signal levels before field deployment.

Medical Patient-Monitoring Front Ends
For ECG, EEG, and pulse-oximetry front ends, the EVAL-AD4030-24FMCZ lets prototyping teams measure how the 24-bit AD4030-24 handles wide dynamic range biological signals. The integrated reference buffer with on-chip decoupling cuts the surrounding bill of materials compared to discrete reference paths. The Easy Drive architecture relaxes the drive-amplifier settle-time requirements, allowing simpler low-power op-amps than competing 24-bit ADCs demand. Combined with a ZedBoard, this board forms a benchtop patient-monitoring prototype suitable for early design verification under IEC 60601 development workflows.

Multichannel Data Acquisition Modules
The EVAL-AD4030-24FMCZ is a baseline board for building multichannel data-acquisition modules where several AD4030-24 ADCs can be synchronised through their CONVST inputs and back-end FPGA logic. The 2 MSPS throughput combined with 24-bit precision allows a 4-board stack of FMC cards to reach 8 MSPS aggregate sample rate at 24 bits. The optional DDR Flexi-SPI clocking eases multi-board synchronisation timing closure on Virtex/UltraScale-class FPGAs. The board's analog front end also demonstrates how to buffer and level-shift a -10 V to +10 V industrial input range into the ADC common-mode input.

Audio-Bandwidth High-Resolution Measurement
When measuring audio-bandwidth signals at 24 bits, the AD4030-24 on the EVAL-AD4030-24FMCZ board supports both high-resolution audio engineering and acoustic test instrumentation. The 2 MSPS rate digitises up to ~920 kHz of baseband while preserving 24-bit noise linearity, far exceeding the 192 kHz needs of typical pro-audio systems. The Flexi-SPI echo-clock mode allows low-jitter data transfer into an FPGA for FFT analysis of audio DAC performance, speaker distortion, or microphone calibration. The board enables direct comparison of AC-vs-DC distortion performance against an Audio Precision analyser without committing to a custom PCB.
推薦
Industrial Closed-Loop Control Systems
The EVAL-AD4030-24FMCZ supports prototyping of industrial servo/control loops where the AD4030-24's zero pipeline delay is the decisive advantage over pipelined ADCs. The on-chip track-and-hold exhibits no latency, making the converter ideal for deterministic feedback control of valves, drives, and precision stages. The Easy Drive front end tolerates wide-input-common-mode swings common in motor-control environments, while the 5 V and 1.8 V POR resets internal logic at power-on for safe startup. Used with a ZedBoard, the board forms a development platform for evaluating control-loop bandwidth and stability under real PWM noise injection.

主要差異化特點
- Lowest-noise single-channel SAR ADC in Analog Devices' 24-bit precision portfolio (對比EVAL-AD4630-24FMCZ)
- Zero pipeline delay (對比Pipelined 24-bit ADCs)
- Easy Drive analog front end (對比Discrete op-amp front ends)
設計說明
Route the FMC connector to the host FPGA with differential 100 Ω impedance-controlled traces. The 2 MSPS Flexi-SPI DDR mode places a 250 ps setup/hold window on data edges, so uncontrolled routing will corrupt the 24-bit noise floor that justifies this ADC. Short the FMC connector directly into the FPGA bank without series components to avoid skim-jitter.
Power the EVAL-AD4030-24FMCZ from a clean linear 5 V regulator rather than the FMC 12 V or 5 V rail when benchtop-characterising AC performance. The AD4030-24's ±0.9 ppm INL guarantee is achieved only when switching-noise coupling through the test bench is below -120 dBc. Use a series ferrite and 10 uF ceramic decap on the 5 V input of the eval board.
Do not assume the Easy Drive analog front end is fully buffered - the device still requires the input amplifier settle to within ±0.5 LSB at 24 bits (≈30 nV at 2 MSPS) before the next conversion begins. Verify with the eval board first by stepping load-cell or DC source cables and observing the INL histogram before committing to a custom layout.
