Analog Devices Inc. EVAL-AD7608SDZ

Overview

EVAL-AD7608SDZ from Analog Devices is a full-featured evaluation board designed to characterize the AD7608 16-bit, 8-channel, simultaneous-sampling SAR ADC. It integrates on-board ADP7104ARDZ-5.0 LDO and ADR421 voltage reference, supports up to 200 kSPS sampling, and connects via 120-way SDP interface (J2) to EVAL-SDP-CB1Z for PC-based control and analysis in industrial data acquisition systems.

For engineers reviewing the EVAL-AD7608SDZ datasheet, EVAL-AD7608SDZ pinout, EVAL-AD7608SDZ application, or EVAL-AD7608SDZ equivalent, this page delivers verified hardware configuration details, software integration requirements, power supply options (J1/J3), link settings (LK1–LK3, SL1–SL7), and channel input mapping (V1–V8) specific to the AD7608 device mounted at U1.

Technical Context

The EVAL-AD7608SDZ implements a standalone, SDP-compatible platform with dedicated analog input terminal blocks (V1–V8), configurable VDRIVE selection (3.3 V or 5 V via LK3), and dual power routing (J1 for 7–9 V wall adapter or J3 for external 7–9 V supply). All signal conditioning and biasing are handled by on-board components including the ADP7104 5 V LDO and ADR421 precision reference.

Hardware link options define core operational modes: LK1 selects main power source, LK2 enables SDP board power delivery from the eval board, and SL1–SL7 route critical digital control signals (CS, SCLK, CONVST, RESET, STBY) either from the SDP board (J2) or SMB connectors - enabling flexible test setup with or without host PC synchronization.

FAQ

What is the target ADC device on the EVAL-AD7608SDZ evaluation board?

The EVAL-AD7608SDZ evaluation board is supplied with the AD7608 16-bit, 8-channel, simultaneous-sampling SAR ADC mounted at U1. This device supports up to 200 kSPS, operates from a single 2.7 V to 5.25 V supply, and features on-board 1 MΩ input buffers - all verified in the UG-851 user guide and AD7608 datasheet. The EVAL-AD7608SDZ is not interchangeable with boards targeting AD7606, AD7607, or AD7605-4 without confirming hardware configuration and firmware compatibility.

Does the EVAL-AD7608SDZ require an external system demonstration platform to operate?

Yes, the EVAL-AD7608SDZ requires the EVAL-SDP-CB1Z system demonstration platform for full functionality. It connects via the 120-way SDP connector (J2), and the SDP board enables USB communication with Windows PCs running the AD7606 evaluation software. Without EVAL-SDP-CB1Z, the EVAL-AD7608SDZ cannot be controlled or acquire data - no standalone data capture capability exists on the board itself.

What power supply options does the EVAL-AD7608SDZ support, and how are they selected?

The EVAL-AD7608SDZ supports two power input paths: J1 (7–9 V dc via 2.0 mm jack, using the supplied wall adapter) and J3 (7–9 V dc terminal block for external supply). Selection is controlled by link LK1: Position A routes power from J1; Position B routes power from J3. Both paths feed the on-board ADP7104 5 V LDO, ensuring regulated bias for the AD7608 and supporting circuitry.

How are analog input channels accessed on the EVAL-AD7608SDZ?

Analog inputs on the EVAL-AD7608SDZ are accessed through eight SMB connectors labeled V1 to V8, each directly routed to one of the eight input channels of the AD7608. Unlike variants such as EVAL-AD7606-4SDZ or EVAL-AD7605-4SDZ, the EVAL-AD7608SDZ fully populates all eight channels - confirmed in UG-851 Section "EVAL-AD7608SDZ" - enabling true 8-channel simultaneous sampling evaluation without channel remapping or jumper reconfiguration.

Which software is used to control the EVAL-AD7608SDZ, and where is it obtained?

The EVAL-AD7608SDZ is controlled using the AD7606 evaluation software, which supports all devices in the AD760x family including the AD7608. The software is provided on the included CD and is also downloadable from the AD7606/AD7606-6/AD7606-4, AD7607, AD7608, and AD7605-4 product pages on analog.com. It provides waveform capture, histogram analysis, FFT spectral analysis, and summary reporting - all validated for use with EVAL-AD7608SDZ in UG-851 Rev. A.
