Overview

The EVAL-CN0535-FMCZ is a data acquisition (DAQ) system that measures real world physical phenomenon such as temperature, force, acceleration, or vibration, converting measurements into digital values for data processing, storage, or transmission to a remote location. A typical DAQ system is comprised of a sensor, analog filtering and signal conditioning circuitry, an analog-to-digital converter (ADC), and digital controller. Components for a DAQ solution are selected on a per application basis. Some DAQ systems are designed to minimize the overall system DC error from sensor, with fast settling filters for control-loop or multiplexed applications. Others are designed to provide superior AC performance, with low distortion and flat frequency response.

Getting Started

The CN0535 can be used for a wide range of applications, and the following demos are meant to show examples of the flexibility of the board. To get started with setup, configuration, and example use cases, please proceed to the provided demo page.

Hardware Setup

Equipment Required

  • CN0535 Circuit Evaluation Board (EVAL-CN0535-FMCZ)

  • System Demonstration Platform Board (EVAL-SDP-CH1Z)

  • AP2700 Signal Source or Equivalent

Hardware Connection

To begin using the evaluation board, take the following steps:

  1. Ensure the EVAL-SDP-CH1Z system demonstration platform board is disconnected from the PC. Install the AD7768-1 Evaluation Board Software. Restart the PC after the software installation is complete.

  2. Connect the EVAL-SDP-CH1Z system demonstration platform board to the EVAL-CN0535-FMCZ reference design board. The J4 connector of the EVAL-SDP-CH1Z system demonstration platform board connects to the receiving socket P1 on the EVAL-CN0535-FMCZ.

  3. Ensure the evaluation boards are securely connected together by tightening the mounting screws.

  4. Connect the 12 V DC power supply to the EVAL-SDP-CH1Z system demonstration platform board, then connect the provided USB cable from the board to the PC. If prompted, allow the operating system to automatically search for and install the EVAL-SDP-CH1Z drivers.

  5. Launch the AD7768-1 evaluation board software from the Analog Devices folder in the Programs menu.

  6. Connect the differential input source to the SMB connectors (J3 and J4). P7 can also be used for a wired source.

Warning

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.
