ADI's AD74413R quad software configurable input / output is a solution for building and process control applications.
This device has functions for analog output, analog input, digital input and resistance temperature detector (RTD). It also includes thermocouple measurements integrated into a single-chip solution via SPI. The device has a 16-bit sigma-delta ADC and four configurable 13-bit DACs. The DAC provides four configurable input / output channels and a suite of diagnostic functions.
Several modes related to the device. These modes are voltage output, voltage input, current output, externally powered current input, loop powered current input, digital input logic, external RTD measurement and loop powered digital input. The device includes a high-precision 2.5V internal reference to drive the DAC and ADC.
