Analog Devices Inc. EVAL-AD7380FMCZ

Overview

EVAL-AD7380FMCZ from Analog Devices is a full-featured FMC-form-factor evaluation board designed to characterize the AD7380 16-bit, dual-channel, simultaneous-sampling SAR ADC. It integrates on-board reference (ADR4533/ADR4525), ADC driver (ADA4896-2), power supplies (ADP7104, ADP7182, ADP166A), and interfaces via SDP-H1 controller (EVAL-SDP-CH1Z) for SPI-based register control and data capture. Used in high-speed precision data acquisition systems requiring 4 MSPS throughput and differential analog inputs.

For engineers reviewing the EVAL-AD7380FMCZ datasheet, EVAL-AD7380FMCZ pinout, EVAL-AD7380FMCZ application, or EVAL-AD7380FMCZ equivalent, this page delivers verified hardware configuration details, ACE software integration workflow, FMC-LPC interface mapping, on-board power rail specifications, and supported ADC variants (AD7380, AD7381, AD4680, AD4681).

Technical Context

The EVAL-AD7380FMCZ implements a complete signal chain for dual-channel, simultaneous sampling ADC evaluation: differential analog inputs routed through ADA4896-2 buffers, selectable internal/external reference (2.5 V or 3.3 V), and programmable oversampling (2×–32×) with 18-bit resolution mode. It supports both AD7380 (4 MSPS) and AD7381 (4 MSPS) at full speed, and adapts to slower AD4680 (1 MSPS) and AD4681 (500 kSPS) via clock/sampling frequency adjustment.

Communication occurs over SPI via the 160-pin SDP connector (J4), with FPGA-based data capture and real-time analysis in ACE software. Power is supplied either by the EVAL-SDP-CH1Z (default) or external sources including ±2.5 V amplifier rails, 3.3 V ADC core, 2.3 V logic, and 12 V main supply - all configurable via solder-jumpers (LK1–LK5, JP1–JP6).

FAQ

What is the primary function of the EVAL-AD7380FMCZ?

The EVAL-AD7380FMCZ is a dedicated FMC-compatible evaluation board for the AD7380 and AD7381 dual-channel, simultaneous-sampling SAR ADCs. It provides a complete, ready-to-use signal chain-including on-board reference, buffer amplifiers, power regulation, and SPI interface-to enable rapid characterization of dynamic performance (SNR, THD, FFT), dc accuracy (INL/DNL), and oversampling behavior. The EVAL-AD7380FMCZ also supports AD4680 and AD4681 with adjusted clocking.

Which controller board is required to operate the EVAL-AD7380FMCZ?

The EVAL-AD7380FMCZ requires the EVAL-SDP-CH1Z (SDP-H1) system demonstration platform controller board for USB-based communication and power delivery. The two boards connect via the 160-way SDP connector (J4). ACE software running on a Windows PC communicates with the EVAL-AD7380FMCZ through the EVAL-SDP-CH1Z's FPGA interface - no standalone operation or alternative controllers are supported per the UG-1304 documentation.

Does the EVAL-AD7380FMCZ support external voltage references?

Yes, the EVAL-AD7380FMCZ supports external voltage references up to 3.3 V via the EXT_REF header. JP4 configures REFIO to accept either the internal ADR4525 (2.5 V) or ADR4533 (3.3 V) reference, or an external source. When using an external reference, the internal reference must be disabled via link configuration, and the reference voltage must be stable and low-noise to preserve ADC performance - as confirmed in UG-1304 Section "Link Configuration Options" and Figure 3.

Can the EVAL-AD7380FMCZ be used without the EVAL-SDP-CH1Z?

No - the EVAL-AD7380FMCZ does not support standalone operation. Its digital interface relies entirely on the EVAL-SDP-CH1Z for SPI communication, clock generation, and FPGA-based data capture. While external power can be applied (e.g., 12 V to P4, ±2.5 V to P6), the board lacks onboard USB, microcontroller, or firmware to manage ADC configuration or data readout independently. UG-1304 explicitly states that communication is achieved "via the 160-way system demonstration platform (SDP) connector, J4" and that the EVAL-SDP-CH1Z is the required controller.

What software is needed to evaluate the EVAL-AD7380FMCZ?

The official ACE (Analysis, Control, Evaluation) software is required to operate the EVAL-AD7380FMCZ. It provides full access to register configuration (Memory Map), real-time waveform capture, histogram analysis, and FFT-based spectral evaluation. ACE includes the AD738x plug-in and supports Windows Vista SP2 through Windows 10 (32/64-bit). Installation must precede hardware connection to ensure proper driver recognition - as detailed in UG-1304 Sections "Software Installation Procedures" and "AD7380/AD7381 Evaluation Software Operation".
