Working Principles

The ADS8695IPWR utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It samples the input voltage, compares it with a reference voltage, and iteratively determines the digital representation by adjusting the binary code until the desired accuracy is achieved. The converted digital data is then made available through the SPI interface.
