Analog Devices Inc. EVAL-AD4002FMCZ

Overview

EVAL-AD4002FMCZ from Analog Devices is a field-programmable gate array (FPGA) mezzanine card (FMC)-compatible evaluation board designed to simplify performance validation of the AD4002 - a 18-bit, 1.8 MSPS precision successive approximation register (SAR) analog-to-digital converter. It integrates on-board ADR4550 5.0 V reference, ADA4807-1 reference and common-mode buffers, dual signal conditioning op amps, and power regulation circuitry for ±VS, VDD, VIO, and VREF rails.

For engineers reviewing the EVAL-AD4002FMCZ datasheet, EVAL-AD4002FMCZ pinout, EVAL-AD4002FMCZ application, or EVAL-AD4002FMCZ equivalent, this page delivers verified hardware interface details, SDP-H1/FMC-LPC connectivity requirements, software-controlled FFT/time-domain analysis capability, and ADC-specific configuration options including SL4 jumper settings for single-ended vs. differential input mode.

Technical Context

The EVAL-AD4002FMCZ interfaces exclusively via a 160-pin FMC low pin count (LPC) connector to the SDP-H1 controller board, which hosts a Xilinx Spartan-6 FPGA and ADSP-BF527 processor. Communication occurs over SPI with CNV, SCK, SDO, and SDI signals routed directly from the FMC to the AD4002 IC.

It supports factory-configured single-ended or pseudo-differential input operation (SL4 = B), uses an ADR4550 buffered 5.0 V reference, and derives ±VS rails from ADP7118 (+7 V), ADP2370/ADM660/ADP7182 (−2.5 V), and 1.8 V/3.3 V digital supplies - all decoupled per device and referenced to a single ground plane.

FAQ

What is the primary function of the EVAL-AD4002FMCZ?

The EVAL-AD4002FMCZ is a dedicated evaluation board for the AD4002 18-bit SAR ADC. It provides complete signal conditioning, precision reference, regulated power rails, and FMC-LPC interface to the SDP-H1 controller - enabling rapid, repeatable dynamic and static performance testing without custom hardware design. The EVAL-AD4002FMCZ eliminates the need for external reference buffers, driver amplifiers, or power sequencing logic during lab validation.

Which controller boards are compatible with the EVAL-AD4002FMCZ?

The EVAL-AD4002FMCZ is designed for use with the SDP-H1 system demonstration platform (EVAL-SDP-CH1Z), which provides SPI communication, FPGA-based timing control, and USB 2.0 PC connectivity. It is also compatible with any FMC-LPC-compliant host controller that supports the required pinout, voltage levels, and SPI protocol timing for the AD4002 - though SDP-H1 remains the only officially supported and software-integrated platform.

Does the EVAL-AD4002FMCZ support differential input configurations?

No - the EVAL-AD4002FMCZ is factory configured for single-ended or pseudo-differential input operation (SL4 = B), matching the AD4002's native input architecture. Unlike the EVAL-AD4001FMCZ or EVAL-AD4003FMCZ, it does not support fully differential input mode. Attempting to force differential operation would require hardware modification and is not validated or recommended per UG-1042.

Can the EVAL-AD4002FMCZ be used to evaluate other AD4000-series ADCs?

Yes - while populated with the AD4002, the EVAL-AD4002FMCZ hardware can evaluate other AD4000-family devices (e.g., AD4000, AD4004, AD4006) by limiting sample rate in the AD40XX software to match the target ADC's maximum throughput. However, full performance validation requires verifying compatibility of reference drive strength, input biasing, and power rail requirements against each specific device's datasheet.

What power supply options does the EVAL-AD4002FMCZ support?

The EVAL-AD4002FMCZ accepts power either from the SDP-H1 board (12 V input, generating internal +7 V, −2.5 V, 1.8 V, and 3.3 V rails) or from an external bench supply via screw terminals J2/J3. When using external power, solder links SL1, SL2, SL5, SL6, SL7, SL8, and SL9 must be set to Position B to isolate onboard regulators - a change explicitly documented in UG-1042 Table 2.
