Analog Devices Inc. EVAL-AD7616-PSDZ

Overview

EVAL-AD7616-PSDZ from Analog Devices is a full-featured evaluation board designed to characterize the AD7616 and AD7616-P 16-channel, 16-bit, dual simultaneous sampling ADCs. It supports ±2.5 V, ±5 V, and ±10 V bipolar input ranges, delivers up to 1 MSPS per channel pair, and integrates on-board ADP7118/ADP7104ARDZ-5.0 LDOs and ADR421 2.5 V reference for standalone operation in power-line monitoring and industrial data acquisition systems.

For engineers reviewing the EVAL-AD7616-PSDZ datasheet, EVAL-AD7616-PSDZ pinout, EVAL-AD7616-PSDZ application, or EVAL-AD7616-PSDZ equivalent, this page provides verified hardware configuration details, SDP-B controller interface requirements, analog input connector mapping (J1–J4), power supply setup (J7/J8/J9), and software-controlled sequencer/oversampling functionality confirmed in UG-1012 Rev. B.

Technical Context

The EVAL-AD7616-PSDZ implements a complete signal chain for the AD7616/AD7616-P, including dual 8-channel analog front-end paths (V0A–V7A and V0B–V7B), on-board 5 V and 3.3 V LDOs (ADP7104ARDZ-5.0 and ADP7118), and an ultraprecise 2.5 V XFET® reference (ADR421). It interfaces exclusively via the 120-pin SDP-B connector (J10) or optionally through J5 SIL header for debug/standalone mode.

Link configuration (LK1–LK41) enables hardware-selectable VCC/VDRIVE sourcing, internal/external reference selection, channel grounding (LK1–LK16), input termination (LK17–LK32), and sequencer/range control (LK33–LK37). Default factory setup uses J7 (7–9 V DC) for power, internal ADR421 reference, and SDP-B parallel interface control.

FAQ

What is the primary function of the EVAL-AD7616-PSDZ?

The EVAL-AD7616-PSDZ is a dedicated evaluation board for the AD7616 and AD7616-P 16-channel, 16-bit, dual simultaneous sampling ADCs. It provides complete hardware and software infrastructure-including on-board power regulation, precision reference, configurable analog inputs, and SDP-B interface-to validate performance metrics such as SNR (90.5 dB), throughput (1 MSPS per channel pair), and oversampling capability (92 dB SNR at OSR = 2) under real-world conditions. The EVAL-AD7616-PSDZ enables rapid prototyping without custom PCB design.

Which ADC variants does the EVAL-AD7616-PSDZ support?

The EVAL-AD7616-PSDZ supports both the AD7616 and AD7616-P devices. While the AD7616 offers SPI/QSPI/MICROWIRE-compatible serial and parallel interfaces, the AD7616-P is parallel-interface-only-matching the EVAL-AD7616-PSDZ's default SDP-B parallel connection via J10. Both share identical analog front-end architecture, 16-channel bipolar input structure, and on-chip sequencer functionality, making the EVAL-AD7616-PSDZ fully compatible with either variant per UG-1012 Rev. B.

What power supplies are required to operate the EVAL-AD7616-PSDZ?

The EVAL-AD7616-PSDZ operates from a single 7 V to 9 V DC input via barrel jack J7, which powers on-board ADP7118 (3.3 V VDRIVE) and ADP7104ARDZ-5.0 (5 V VCC) LDOs. Alternatively, external VCC (5 V ±10% via J9) and VDRIVE (2.3 V to 3.6 V via J8) can be supplied. Link settings LK40 and LK41 determine source selection; default factory configuration uses J7 for both rails. No additional power sources are needed for basic operation.

How is analog input configured on the EVAL-AD7616-PSDZ?

Analog inputs on the EVAL-AD7616-PSDZ are organized across four connectors: J1 (V0A–V3A), J2 (V4A–V7A), J3 (V0B–V3B), and J4 (V4B–V7B), supporting 16 total bipolar channels. Input range (±2.5 V, ±5 V, or ±10 V) is selected per channel via software or hardware links LK36–LK37. Grounding and termination are controlled by jumpers LK1–LK32: inserted LK1–LK16 connect channel grounds to board AGND; removed LK17–LK32 disconnect 270 Ω input resistors for direct signal injection.

What software and host requirements are needed for the EVAL-AD7616-PSDZ?

The EVAL-AD7616-PSDZ requires Analog Devices' AD7616 evaluation software (Windows XP SP3, Vista, or Windows 7, USB 2.0 port) and the EVAL-SDP-CB1Z controller board with its drivers. Software features include real-time waveform capture, FFT/histogram analysis, sequencer stack programming, register-level control, and oversampling ratio configuration. The EVAL-AD7616-PSDZ itself does not run firmware-it relies entirely on PC-hosted software and SDP-B communication for all configuration and data acquisition tasks.
