Product Details
The 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.
