AD74412RBCPZ-RL7

AD74412R is a quad-channel software configurable input/output solution for building and process control applications. It contains functionality for analogue output, analogue 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). This device features a 16bit, Σ-∆ analogue-to-digital converter (ADC) and four configurable, 13bit digital-to-analogue converters (DACs) to provide four configurable input/output channels and a suite of diagnostic functions. There are several modes related to the device. 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. It is used in applications such as building control systems, process control, industrial automation.
