Analog Devices Inc. EVAL-ADAS3022EDZ

Overview

EVAL-ADAS3022EDZ from Analog Devices is an evaluation board designed specifically for the ADAS3022 16-bit, 8-channel, 1 MSPS data acquisition system (DAS). It integrates on-board signal conditioning, a buffered 4.096 V reference (ADR434), clock oscillator, FPGA-based serial interface handling, and analog input test points for IN[7:0] and COM - enabling full characterization of high-precision sensor-to-digital conversion in industrial and instrumentation applications.

For engineers reviewing the EVAL-ADAS3022EDZ datasheet, EVAL-ADAS3022EDZ hardware setup, EVAL-ADAS3022EDZ software operation, or EVAL-ADAS3022EDZ compatibility with EVAL-CED1Z, this page delivers verified technical context, key specifications, supply support, and manufacturer-specific design intent - all grounded in the official UG-484 user guide and Analog Devices' documented board architecture.

Technical Context

The EVAL-ADAS3022EDZ interfaces directly with the ADAS3022 DAS via a 4-wire SPI-compatible serial interface (CS, DIN, SCK, SDO), controlled by an on-board Altera FPGA (U6) that deserializes conversion results and configures device registers. It supports ±15 V analog supplies (VDDH/VSSH), local LDOs for 1.2 V (FPGA core), 2.5 V/3.3 V/5 V (digital/analog rails), and flexible reference selection - internal 4.096 V, external ADR434, or buffered 2.5 V → 4.096 V using AD8032.

Hardware configuration requires the EVAL-CED1Z USB capture board connected via P4 (96-pin edge connector), while analog inputs are accessible through test points (IN0_I to IN7_I) and configurable COM routing (P31 jumper). Signal integrity is preserved via NPO/COG RC filtering footprints and strict analog/digital ground separation across its 6-layer PCB layout.

FAQ

What is the primary function of the EVAL-ADAS3022EDZ?

The EVAL-ADAS3022EDZ is an evaluation board designed exclusively for the ADAS3022 16-bit, 8-channel, 1 MSPS data acquisition system. Its purpose is to demonstrate full device performance, provide a ready-to-use interface for analog input testing, and enable rapid development of precision measurement systems - including time-domain analysis, FFT-based SNR/SINAD/THD evaluation, and histogram-based code transition noise assessment using bundled PC software.

Which companion board is required to operate the EVAL-ADAS3022EDZ?

The EVAL-CED1Z converter evaluation and development board is mandatory for operating the EVAL-ADAS3022EDZ. It serves as the USB-connected controller that captures serial output from the ADAS3022 via the 96-pin P4 interface, translates it into parallel data, and communicates with the PC-hosted evaluation software. Without EVAL-CED1Z, the EVAL-ADAS3022EDZ cannot acquire or process conversion data.

Does the EVAL-ADAS3022EDZ include its own power supplies for the ADAS3022?

No - the EVAL-ADAS3022EDZ does not include ±15 V supplies required for the ADAS3022's VDDH and VSSH pins. These must be provided externally using a lab bench supply. However, the board integrates ADP3334 and ADP1715 LDOs to generate +1.2 V (FPGA core), +2.5 V, +3.3 V, and +5 V rails, and supports optional power injection from the EVAL-CED1Z board for +5 V analog/digital and ±5 V analog rails.

How is the reference voltage configured on the EVAL-ADAS3022EDZ?

Reference configuration on the EVAL-ADAS3022EDZ is managed via two three-pin jumpers: P5 (REFIN select) and P9 (REF select). Factory default uses the on-board ADR434 (4.096 V) buffered by AD8032 (P5 = REFIN to GND, P9 = REF to BUF). Alternatives include internal 4.096 V reference (both jumpers open), unbuffered external reference (remove P9), or 2.5 V input to REFIN with internal buffer enabled (P5 = open, P9 = open, register bit set).

Can the FPGA on the EVAL-ADAS3022EDZ be bypassed for custom digital control?

Yes - the on-board Altera FPGA (U6) can be fully bypassed using factory-configured solder pads (P9–P29). Each digital signal (CNV, BUSY, SDO, etc.) connects by default between the FPGA and ADAS3022; resoldering from the large pad to the labeled "_I" pad (e.g., CNV_I) routes that signal to the P3 40-pin IDC header instead. This allows direct connection to external controllers or logic without FPGA involvement while keeping the FPGA powered but inactive.
