Analog Devices Inc. EVAL-AD7352EDZ

Overview

EVAL-AD7352EDZ from Analog Devices is a dedicated evaluation board for the AD7352 dual 12-bit simultaneous-sampling SAR ADC, supporting differential input, on-board analog buffering via AD8138, precision 2.5 V ADR421 references, and 96-way edge connector interface to EVAL-CED1Z. It enables rapid characterization of AC/DC performance up to 3 MSPS in lab or design validation environments.

For engineers reviewing the EVAL-AD7352EDZ datasheet, EVAL-AD7352EDZ pinout, EVAL-AD7352EDZ application, or EVAL-AD7352EDZ equivalent, this page delivers verified hardware configuration details, supported signal paths (SDATAA/SDATAB, SCLK, CS), link option settings for standalone vs. CED1Z operation, and software-controlled FFT/histogram/linearity analysis workflows.

Technical Context

The EVAL-AD7352EDZ implements a complete analog front-end for dual-channel simultaneous sampling: two AD8138 single-ended-to-differential converters condition VA/VB inputs, while dual ADR421 2.5 V references supply REFA/REFB. Power domains are strictly separated with dedicated AGND/DGND planes tied at one point near the AD7352.

It supports two operational modes: fully integrated with EVAL-CED1Z (providing VDD, VDRIVE, SCLK, CS, SDATAA/SDATAB via 96-way J1) or standalone (with external supplies via J11/J12/J14 and configurable solder links S1–S24). Link options LK1–LK4 and S1–S24 define signal routing, termination (49.9 Ω), reference source, and common-mode selection.

FAQ

What is the primary purpose of the EVAL-AD7352EDZ?

The EVAL-AD7352EDZ is a dedicated evaluation board for the AD7352 dual 12-bit simultaneous-sampling SAR ADC. Its purpose is to enable engineers to rapidly evaluate AC/DC performance-including SNR, THD, INL, DNL, and FFT spectra-under real-world signal conditions using either the EVAL-CED1Z controller or standalone external supplies. It is not intended for production use.

Which ADC models does the EVAL-AD7352EDZ support?

The EVAL-AD7352EDZ is explicitly designed for the AD7352, AD7356, and AD7357 families. While it supports all three, its default configuration and documented 3 MSPS throughput limit apply specifically to the AD7352. The board's hardware-including AD8138 buffers, ADR421 references, and link options-is validated for all three parts, but performance parameters (e.g., max sample rate) vary per device.

How does the EVAL-AD7352EDZ connect to a host system?

The EVAL-AD7352EDZ connects via a 96-way edge connector (J1) to the EVAL-CED1Z controller board, which then interfaces to a PC via USB 2.0. This path delivers power (VDD, VDRIVE, ±5 V), clocks (SCLK), control (CS), and data (SDATAA/SDATAB). Standalone operation requires external supplies and signals routed through SMB connectors (J7–J10, J3–J6) and power headers (J11–J14).

What software is provided with the EVAL-AD7352EDZ?

The EVAL-AD7352EDZ ships with Windows-compatible software (XP/2000) for controlling the EVAL-CED1Z and performing real-time analysis: waveform capture, histogram generation, FFT spectral analysis, and linearity testing (INL/DNL). It includes FPGA configuration loading, sampling rate selection (up to 3 MSPS for AD7352), and dual-ADC channel switching (VA/VB ON/OFF).

Can the EVAL-AD7352EDZ operate without the EVAL-CED1Z?

Yes - the EVAL-AD7352EDZ supports standalone operation. External power must be supplied via J11 (VDD/AGND), J12 (VDRIVE/DGND), and J14 (±5 V/AGND), and control signals (SCLK, CS) and data paths (SDATAA/SDATAB) must be driven externally via SMB connectors J7–J10. All required link options (LK1–LK4, S1–S24) must be manually configured per the Hardware Setup section of the user guide.
