The Analog Devices AD74413R Quad-Channel Software Configurable Input/Output is a solution for building and process control applications.

The device comprises functionality for analog output, analog input, digital input, and resistance temperature detector (RTD). It also includes thermocouple measurements integrated into a single chip solution with an SPI. The device features a 16-bit, Σ-Δ ADC, and four configurable, 13-bit DACs. The DACs provide four configurable input/output channels and suite of diagnostic functions.

There are several modes related to device. These modes are voltage output, voltage input, current output, externally powered current input, loop-powered current input, digital input logic, external RTD measurement, and loop-powered digital input. The device includes a high accuracy 2.5V internal reference to drive the DACs and the ADC.
