Product details
Overview
EVAL-AD7171EBZ from Analog Devices is a USB-powered evaluation board designed to demonstrate and validate the AD7171 16-bit, low-power sigma-delta ADC. It features an on-board ADP3330 3.3 V regulator, standalone USB interface (CY7C68013A), and supports differential analog input with 125 Hz output data rate. The board enables noise analysis, reference configuration flexibility, and real-time waveform visualization via PC software.
For engineers reviewing the EVAL-AD7171EBZ datasheet, EVAL-AD7171EBZ pinout, EVAL-AD7171EBZ application, or EVAL-AD7171EBZ equivalent, this page provides verified hardware setup details, USB/SPI interface behavior, link configuration options, software-controlled sampling modes (single/continuous), and LabVIEW™-based analysis capabilities for precision ADC validation in portable and battery-powered systems.
Technical Context
The EVAL-AD7171EBZ implements a complete signal chain around the AD7171BCPZ - including AVDD/REFIN sourcing via selectable links (J1, J8, AGND), analog input routing through J4 terminal block, and external reference injection via J5. Power is derived from USB 5 V (J51) or external supply (J6), regulated to 3.3 V by U53 (ADP3330ARZ-3.3).
Communication uses a Cypress CY7C68013A-56LFXC USB microcontroller interfacing to the AD7171 via SPI, with configuration and data capture managed by Analog Devices' dedicated Windows® software. Link J2 enables/disables MCU-to-ADC SPI connection, while J3/J7 short AIN(+) and AIN(−) to AVDD/2 for noise testing.

FAQ
What is the primary function of the EVAL-AD7171EBZ?
The EVAL-AD7171EBZ is a dedicated evaluation board for the AD7171 16-bit sigma-delta ADC. It provides a complete, USB-powered test environment with configurable analog input, reference, and power options - enabling rapid characterization of the AD7171BCPZ's performance, including noise analysis, linearity verification, and output data rate validation under real-world conditions. The EVAL-AD7171EBZ does not replace the AD7171 but serves exclusively as its hardware validation platform.
Does the EVAL-AD7171EBZ require an external power supply?
No, the EVAL-AD7171EBZ operates directly from the host PC's USB 5 V supply via connector J51. An external power source is optional and only needed when testing specific AVDD or reference configurations beyond USB-derived 3.3 V - such as using J6 for 3 V or 5 V external supply, or J5 for alternate reference voltage injection. All default operation is self-contained via USB.
How is communication between the PC and the AD7171 established on the EVAL-AD7171EBZ?
Communication uses an on-board Cypress CY7C68013A-56LFXC USB microcontroller that bridges USB 2.0 commands to SPI signals routed to the AD7171BCPZ. The EVAL-AD7171EBZ requires pre-installation of Analog Devices' Windows® evaluation software, which handles register configuration, sample acquisition, and real-time data visualization without requiring custom driver development or firmware modification.
Can the EVAL-AD7171EBZ be used with other ADCs besides the AD7171?
No - the EVAL-AD7171EBZ is specifically laid out and calibrated for the AD7171BCPZ. Its schematic, component selection (e.g., ADR391 reference, ADP3330 regulator, link topology), and software stack are optimized for that device's pinout, timing, and register map. Substituting another ADC - even from the same family - is not supported and would require redesign of power, reference, and interface circuitry.
What software tools are included with the EVAL-AD7171EBZ?
The EVAL-AD7171EBZ ships with Analog Devices' proprietary Windows® evaluation software, distributed on CD and available for download. This software provides a GUI for configuring the AD7171BCPZ (gain, filter, data rate), acquiring samples (single or continuous), performing noise analysis (p-p, rms), generating histograms and waveforms, and exporting data to Excel or MathCAD™. No third-party IDE or SDK is required to operate the EVAL-AD7171EBZ.
