+description: |
+  The AD74413R and AD74412R are quad-channel software configurable input/output
+  solutions for building and process control applications. They contain
+  functionality for analog output, analog input, digital input, resistance
+  temperature detector, and thermocouple measurements integrated
+  into a single chip solution with an SPI interface.
+  The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide
+  four configurable input/output channels and a suite of diagnostic functions.
