Analog Devices Inc. EVAL-ADAS3023EDZ

Overview

EVAL-ADAS3023EDZ from Analog Devices is an evaluation board designed specifically for the ADAS3023 16-bit, 8-channel simultaneous sampling data acquisition system (DAS). It provides full hardware and software support for evaluating the ADAS3023's differential input ranges (±2.56 V to ±20.48 V), 500 kSPS throughput, and on-chip PGIA with high common-mode rejection in channel-to-COM configurations.

For engineers reviewing the EVAL-ADAS3023EDZ datasheet, EVAL-ADAS3023EDZ pinout, EVAL-ADAS3023EDZ application, or EVAL-ADAS3023EDZ equivalent, this board enables rapid validation of high-precision analog front-end performance in industrial process control, power quality monitoring, and test instrumentation systems requiring synchronized multi-channel acquisition without latency.

Technical Context

The EVAL-ADAS3023EDZ interfaces directly with the EVAL-CED1Z USB-based capture board via a 96-pin edge connector (P4) and relies on external ±15 V supplies for the ADAS3023's high-voltage analog section. Its on-board FPGA (U6) handles serial-to-parallel deserialization, CNV timing generation, and ADAS3023 configuration via a 4-wire SPI-compatible interface.

Signal conditioning includes passive RC filtering (22 Ω + 2700 pF NPO), a buffered ADR434 4.096 V reference (with AD8032 buffer), and configurable jumpers for reference selection (P5/P7), COM routing (P31), and digital signal routing (P9–P29). The board supports both internal and external reference modes and allows FPGA bypass via solder pad rework.

FAQ

What is the primary function of the EVAL-ADAS3023EDZ?

The EVAL-ADAS3023EDZ is a dedicated evaluation board for the ADAS3023 16-bit, 8-channel simultaneous sampling data acquisition system. It provides complete hardware infrastructure-including analog signal conditioning, reference circuitry, FPGA-based interface logic, and PC software-to validate the ADAS3023's performance in real-world applications such as power quality monitoring and industrial process control. The EVAL-ADAS3023EDZ enables users to configure input ranges, sample rates, and reference sources without custom PCB design.

Does the EVAL-ADAS3023EDZ include its own power supply?

No, the EVAL-ADAS3023EDZ requires external ±15 V supplies for the ADAS3023's high-voltage analog section (VDDH and VSSH pins), as explicitly stated in the UG-515 User Guide. It does not generate ±15 V onboard. Lower-voltage rails (+5 V analog/digital, +3.3 V, +2.5 V, +1.2 V) are provided by on-board regulators (ADP3334, ADP1715) or sourced from the EVAL-CED1Z board via the 96-pin interface. The EVAL-ADAS3023EDZ must be powered externally before connection to the PC.

Which companion board is required to operate the EVAL-ADAS3023EDZ?

The EVAL-CED1Z converter evaluation and development board is mandatory for operation of the EVAL-ADAS3023EDZ. The EVAL-ADAS3023EDZ connects to the EVAL-CED1Z via a 96-pin edge connector (P4) and relies on it for USB communication, clock distribution, and digital power delivery. Without the EVAL-CED1Z, the EVAL-ADAS3023EDZ cannot interface with a host PC or acquire data - the EVAL-CED1Z serves as the controller and data capture interface for the EVAL-ADAS3023EDZ.

Can the EVAL-ADAS3023EDZ be used without the FPGA?

Yes, the EVAL-ADAS3023EDZ supports FPGA bypass via factory-configured solder pads (P9–P29). By reworking these pads, users can route ADAS3023 control signals (CNV, BUSY, SDO, DIN, SCK, CS, RESET, PD) directly to the 40-pin IDC header (P3), enabling external microcontroller or FPGA control independent of the on-board Altera FPGA (U6). The FPGA remains powered but inactive when all digital signals are rerouted, giving full flexibility for custom interface development.

What reference options does the EVAL-ADAS3023EDZ support for the ADAS3023?

The EVAL-ADAS3023EDZ supports three reference configurations: (1) the ADAS3023's internal 4.096 V reference (enabled via register setting), (2) the on-board ADR434 4.096 V reference in buffered mode (via AD8032 U20), or (3) an external 2.5 V source applied to REFIN, which the ADAS3023 internally buffers to 4.096 V. Jumper settings P5 and P7 determine selection, and all modes are validated in UG-515. The EVAL-ADAS3023EDZ does not support arbitrary external references outside these defined topologies.
