The AD74412R and AD74413R 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. The AD74413R differentiates itself from the AD74412R by being HART-compatible.
