Overview

The EVAL-AD4110-1SDZ is the evaluation board for the AD4110-1, a complete, single-channel, universal input analog-to-digital front end for industrial process control systems where sensor type flexibility is required.

The high voltage input is fully software configurable for current or voltage ranges and allows direct interface to all standard industrial analog signal sources such as ±20 mA, ±4 mA to ±20 mA, ±10 V, and all thermocouple types. Field power can be supplied for loop powered current output sensors. The high voltage input can be programmed to power up in either voltage or current mode.

The AD4110-1 provides internal front-end diagnostic functions to indicate overvoltage, undervoltage, open wire, overcurrent, and overtemperature conditions. The high voltage input is overcurrent limited and overvoltage protected up to ±30 V.

The AD4110-1 incorporates a precision 24-bit, Σ-Δ ADC offering conversion rates from 5 SPS to 125 kSPS with simultaneous 50 Hz and 60 Hz noise rejection.

  • 2 software programmable input terminals

    • Current: up to ±20 mA

    • Voltage: up to ±10 V

    • Thermocouple

  • Fast and flexible output data rates: 5 SPS to 125 kSPS

  • Simultaneous 50 Hz and 60 Hz noise rejection

  • 4-wire SPI compatible interface (SPI, QSPI, MICROWIRE, DSP)

  • Power supply: ±12 V to ±20 V, +5 V

Applications:

  • Industrial process control (PLC, DCS)

  • Remote and distributed control systems

  • Data acquisition

  • Instrumentation and measurement

  • Sensor interface

Recommendations

People who follow the flow that is outlined have a much better experience. However, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone, but please read our documentation thoroughly first.

To better understand the AD4110-1, we recommend using the EVAL-AD4110-1SDZ evaluation board with the SDP-B controller board and the AD4110-1 evaluation software on Windows, or the Digilent ZedBoard with the ADI HDL reference design and No-OS evaluation.

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.
