Buy Now View Details

Features and Benefits

  • Quad-channel, software configurable input and output functionality for the AD74413R and the MAX14906
  • Single, 24 V external supply
  • On-board MAX14483, 6-channel, low power, 3.75 kV RMS SPI digital isolator
  • On-board MAX17552, 60 V, 100 mA, ultrasmall, high-efficiency, synchronous step-down DC-to-DC converter
  • Windows GUI for control

Product Details

The EVAL-AD74413R-DIOZ (see Figure 1 in the user guide) is an evaluation board used to demonstrate and evaluate the full software configurable input and output (SWIO) features that the AD74413R and the MAX14906 provide when working together. The board has functionality for digital input, digital output, analog input, and analog output. The EVAL-AD74413R-DIOZ is controlled with a USB2PMB2 adapter board. The USB2PMB2 board controls the EVAL-AD74413R-DIOZ board via the USB port of a PC using the AD74413R-DIOZ demo software.

The EVAL-AD74413R-DIOZ requires an analog power (AVDD) operating supply of 14 V to 28.8 V. The USB2PMB2 board is supplied from the PC.

See the AD74413R data sheet for more information about the AD74413R, and see the MAX14906 data sheet for more information about the MAX14906. Users must consult both data sheets in conjunction with the user guide when using the EVAL-AD74413RDIOZ.

AD-SWIOT1L-SL

Software-configurable Analog and Digital I/O with 10BASE-T1L Evaluation and Development Platform

Buy Now View Details

Features and Benefits

  • Allows prototyping of intelligent, secure, and connected process control devices
  • Ultimate flexibility in I/O interface configurability through software
  • Embedded processing for implementing self-capable edge devices
  • Long-range single-pair 10BASE-T1L Ethernet interface
  • Power delivery via the 10BASE-T1L interface or from a field supply enabling both low and high power applications
  • Fully isolated design for safe operation
  • Industry standard form factor compatible with DIN rail mounts

Product Details

The AD-SWIOT1L-SL provides a complete software and hardware platform for prototyping intelligent, secure, network capable field devices.

The design incorporates the AD74413R Quad-Channel, Software Configurable Input and Output and the MAX14906 Quad-Channel Industrial Digital Output/Digital Input ICs, allowing the multiplexing of several analog and digital functions on four channels which can be independently configurable through software to act as:

  • voltage output / input
  • current output / input
  • digital input / output
  • RTD measurement

A 10 Mbps single-pair Ethernet link, using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and device configuration. The 10BASE-T1L interface can also be used for powering the system via the Single-pair Power over Ethernet (SPoE) technology using the LTC9111 Powered Device (PD) controller. This way, power and data for the system is provided over the same cable to significantly simplify the cabling infrastructure and cost.

For applications requiring high current capabilities, the system can be powered from an external 24 V supply and up to 1.2 A can be output on any of the channels configured as digital outputs. The power supply solution also includes the ADP1032 high performance, isolated micropower management unit (PMU) to provide power and digital control for software configurable I/O devices in one of the most compact formats. The LT8304 Micropower No-Opto Isolated Flyback Converter completes the power tree to provide isolated power to the digital part of the design.

The on-board MAX32650 Ultralow Power ARM® Cortex®-M4 Microcontroller exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with a 1 Gb (128 MB) external RAM and a 64 Mb (8 MB) external flash memory to meet the most demanding applications and provide the flexibility to implement any protocol stack. Security features are enabled by the MAXQ1065 security coprocessor.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation and prototyping all the way to production firmware and applications development. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug. The system’s firmware is based on Analog Devices’ open-source no-OS framework which includes all the tools required for embedded code development and debugging as well as libraries enabling host-side connectivity for system configuration and data transfer over the UART or the 10BASE-T1L interfaces. A PC application with a user-friendly graphical interface is provided to enable easy system configuration and displaying the acquired data in different ways.

Features and Benefits

  • Fully featured evaluation board for the AD74413R
  • On-board 2.5 V ADR4525 reference
  • SPI-compatible
  • PC-based software for control

Product Details

The EV-AD74413RSDZ is a fully featured evaluation board that can be used to evaluate the features of the AD74413R. The AD74413R is a quad-channel, software configurable, input and output device. The device has functionality for analog output, analog input, digital input, and resistance temperature detector (RTD) measurements integrated into a single chip solution with a serial peripheral interface (SPI).

The EV-AD74413RSDZ can be controlled via a system demonstration platform (SDP). The SDP-S controls the EV-AD74413RSDZ via the USB port of a PC using the AD74413R evaluation software.

The EV-AD74413RSDZ requires an AVDD operating supply of 14 V to 28.8 V. When the EV-AD74413RSDZ is connected to the PC, the PC powers the SDP-S.

See the AD74413R data sheet for more information about the AD74413R, and users must consult the data sheet in conjunction with this user guide when using the EV-AD74413RSDZ.
