Analog Devices Inc. EVAL-AD7606EDZ

Overview

EVAL-AD7606EDZ from Analog Devices is an evaluation board for the AD7606 8-channel, 16-bit, simultaneous-sampling analog-to-digital data acquisition system (DAS), supporting ±10 V/±5 V bipolar inputs, 200 kSPS per channel throughput, and flexible parallel/serial/SPI-compatible digital interface. It enables rapid prototyping of high-accuracy power-line monitoring, motor control, and industrial data acquisition systems.

For engineers reviewing the EVAL-AD7606EDZ datasheet, EVAL-AD7606EDZ setup, EVAL-AD7606EDZ hardware configuration, or EVAL-AD7606EDZ compatibility with AD7606-family ADCs, this board provides validated signal chain reference design, jumper-configurable input ranges, on-board reference and power regulation, and PC-based software control via USB interface - critical for functional validation before custom PCB integration.

Technical Context

The EVAL-AD7606EDZ implements a complete, ready-to-run evaluation platform for the AD7606 IC, featuring a precision ±10 V/±5 V analog front-end with clamp protection, second-order anti-aliasing filter, and 1 MΩ input impedance. It integrates the AD7606's full digital interface options - parallel, byte-mode, and SPI/QSPI/MICROWIRE - with configurable VDRIVE (2.3–5.25 V) and logic-level translation.

Board-level design includes on-board 2.5 V reference (internal/external selectable), regulated 5 V analog supply, isolated USB-to-parallel bridge (FTDI-based), and header-accessible signals for CONVST, BUSY, OS[2:0], and all DB[15:0] lines - enabling direct timing analysis, oversampling verification, and real-time waveform capture in lab or production test environments.

FAQ

What is the primary function of the EVAL-AD7606EDZ?

The EVAL-AD7606EDZ is a fully assembled and tested evaluation board for the AD7606-series 16-bit, 8-/6-/4-channel simultaneous-sampling ADCs. It provides immediate hardware validation, signal integrity assessment, and firmware interface testing - eliminating the need for custom carrier board development during early-stage DAS design. The EVAL-AD7606EDZ supports all key features of the AD7606, including bipolar input ranges, oversampling, and multiple digital interface modes.

Does the EVAL-AD7606EDZ support all three AD7606 variants (AD7606, AD7606-6, AD7606-4)?

Yes, the EVAL-AD7606EDZ is compatible with the AD7606 (8-channel), AD7606-6 (6-channel), and AD7606-4 (4-channel) devices. Its layout accommodates the identical 64-lead LQFP package and shared pinout across all variants. Jumper settings and software configuration allow seamless switching between channel counts and associated timing parameters without hardware modification. The EVAL-AD7606EDZ documentation explicitly lists support for all three parts.

What interface options does the EVAL-AD7606EDZ provide for host connection?

The EVAL-AD7606EDZ connects to a host PC via USB 2.0 using an integrated FTDI USB-to-parallel bridge IC. This provides a virtual COM port interface for Analog Devices' evaluation software (ACE), enabling register-level control, real-time waveform plotting, and automated test scripting. All digital interface modes - parallel, byte, and serial - are accessible through onboard headers for direct FPGA or microcontroller integration during system-level validation.

Can the EVAL-AD7606EDZ operate with external reference sources?

Yes, the EVAL-AD7606EDZ supports both internal and external reference configurations. A REF SELECT jumper allows selection between the on-board 2.5 V reference (±10 ppm/°C drift) and an external reference applied to the REFIN/REFOUT pin. When external reference is selected, the internal reference is disabled, and the board routes the external voltage directly to the AD7606's reference input - preserving accuracy for metrology-grade applications requiring traceable calibration standards.

Is oversampling functionality verified and accessible on the EVAL-AD7606EDZ?

Yes, oversampling is fully implemented and testable on the EVAL-AD7606EDZ. Three OS[2:0] jumpers configure the oversampling ratio (2× to 64×), and the board's ACE software displays real-time SNR improvement (e.g., +1.5 dB at 16× oversampling). Timing waveforms for OS-enabled conversions - including extended tCONV and filtered output - are measurable at test points, confirming correct digital filter operation as specified in the AD7606 datasheet Rev.
