		description: \|
		The AD74115H is a single-channel software configurable input/output
		device for industrial control applications. It contains functionality for
		analog output, analog input, digital output, digital input, resistance
		temperature detector, and thermocouple measurements integrated into a single
		chip solution with an SPI interface. The device features a 16-bit ADC and a
		14-bit DAC.
