AD74412R Quad Channel Software Configurable I/O
Analog Devices' AD74412R provides four configurable input/output channels and a suite of diagnostic functions
Analog Devices' AD74412R is a quad-channel software-configurable input/output solution for building and process control applications. The AD74412R contains functionality for analog output, analog input, digital input, and resistance temperature detector (RTD) measurements integrated into a single chip solution with an interface compatible with the serial port interface (SPI).
The device features a 16-bit, Σ-∆ 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 AD74412R. 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 AD74412R contains a high accuracy 2.5 V internal reference to drive the DACs and the ADC.
