Analog Devices AD74413R Quad-Channel Software Configurable Input/Output solution for building and process control applications. AD74413R contains functionality for analog output, analog input, digital input, and resistance temperature detector (RTD). It also contains thermocouple measurements integrated into a single chip solution with a serial peripheral interface (SPI). The device features a 16-bit, Σ-Δ analog-to-digital converter (ADC), and four configurable, 13-bit digital-to-analog converters (DACs). The DACs provide four configurable input/output channels and a suite of diagnostic functions. There are several modes related to AD74413R. These modes are voltage output, current output, voltage input, externally powered current input, loop-powered current input, external RTD measurement, digital input logic, and loop-powered digital input. AD74413R contains a high accuracy 2.5V internal reference to drive the DACs and the ADC.
Create Value with More Integration in Building Automation Controllers Through integration and design reusability, Software-configurable I/O brings innovation to the building automation market. While being traditionally conservative, it is now being pushed to become more agile and respond to ever-changing customer needs more rapidly.
Software Configurable Hardware Helps for Flexibility in Industrial I/O Modules With the right Software configurable I/O ICs, manufacturers can develop a platform that replaces multiple aging fixed function I/O modules. Moreover, they can use this technology across multiple end applications where the I/O dynamically changes with each installation.
