EVAL-AD4060/AD4062-ARDZ

https://media.githubusercontent.com/media/analogdevicesinc/documentation/main/docs/solutions/reference-designs/ad4062-ardz/eval-angle.png

The EVAL-AD4060-ARDZ and EVAL-AD4062-ARDZ evaluation boards enable quick and easy evaluation of the performance and features of the AD4060 or the AD4062, respectively.

The AD4060 and AD4062 are compact, low power, 12-bit or 16-bit (respectively) Easy Drive successive approximation register (SAR) analog-to-digital converters (ADCs) featuring an I3C digital interface. These devices offer exceptional performance with sample rates up to 2 MSPS while maintaining low power consumption, making them ideal for battery-powered precision measurement and monitoring applications.

The evaluation boards are designed to conform to the Arduino Uno Shield mechanical and electrical standard, enabling easy integration with various controller boards and development platforms.

Hardware

The evaluation board connects to the Arduino Uno compatible headers of the carrier board, providing both power and digital communication.

Power Configuration:

When powering from the carrier USB:

  • Set JP2 jumper on the evaluation board to the +5V position

  • Connect carrier to PC via USB

  • The DS1 LED on the evaluation board should illuminate

When using an external power supply:

  • Set JP2 jumper on the evaluation board to the VIN position

  • Provide 7-12V DC to the carrier’s external power input

  • Connect carrier to PC via USB for communication

  • The DS1 LED on the evaluation board should illuminate

I3C Address Configuration:

The evaluation board includes jumpers JP10, JP11, and JP12 to configure the I3C device address via ADDR[2:0] pins. Default firmware requires all address pins set to GND (ADDR[2:0] = 000).

For detailed hardware specifications, schematics, and board layout, see the EVAL-AD4060-ARDZ and EVAL-AD4062-ARDZ product pages, including the user guide and design support files.

Overview

This section summarizes all source code and related documentation for the evaluation board.

Working with the source code requires prior knowledge of software development and HDL design (for FPGA-based carriers). We provide pointers to introductory guides, though their scope is limited to topics particularly relevant to our codebase and do not replace the full documentation of the tools used.

Note

The Linux driver is currently under review for upstream inclusion in the mainline kernel. See the patch series on linux-iio mailing list for the latest status.

Driver Architecture:

  • no-OS: The driver is divided into a core driver (device control) and a TinyIIO layer (IIO interface for Libiio connectivity over serial). The core driver supports both SPI (AD405x) and I3C (AD406x) variants.

  • Linux: The driver is integrated into the IIO subsystem and always exposes the device via Linux Industrial I/O Subsystem. It provides full support for IIO triggers, events, buffers, and GPIO control.

HDL reference design

The FPGA-based carriers (Cora Z7S, DE10-Nano) use an HDL design to instantiate the I3C controller and interface with the evaluation board.

Project source:

Features:

  • I3C controller with offload support*

  • PWM generator for periodic sampling

  • Integration with the HDL Reference Designs framework

  • AXI DMA for high-throughput data capture

Get started with the HDL reference design by reading the User Guide.

* Offload is not supported by the Linux driver.

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
