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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
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.
