- * @brief	MAX8614X - supports MAX8614X object with SPI interface
- * @details	The MAX8614X is a complete integrated optical data acquistion
- * 	system, ideal for optical pulse oximetry and heart rate detection
- * 	applications. High resolution optical readout signal processing channels
- * 	with ambient light cancellation and high current LED driver DACS form a
- * 	complete optical readout signal chain. Features are ultra-low power heart
- * 	rate monitoring, SpO2 monitoring, SmO2 & StO2 detection.
- * 	Typical applications are for wearable devices, fitness devices, clinical
- * 	monitoring, partical detection.
