Quad-Channel, Software Configurable Input and Output

The AD74413R is a quad-channel software configurable input/output solution for building and process control applications. The AD74413R contains functionality for analog output, analog input, digital input, resistance temperature detector (RTD), and 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) to provide four configurable input/output channels and a suite of diagnostic functions.

There are several modes related to the 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.

The AD74413R contains a high accuracy 2.5 V internal reference to drive the DACs and the ADC.
