Working Principles
The AD7823YRMZ is an 8-channel, 12-bit ADC that converts analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high resolution and accuracy. The input voltage range is determined by the reference voltage (VREF) provided externally. The ADC samples the analog input channels using an on-chip track-and-hold circuitry, and the converted digital data is then transmitted serially through the SDATA pin.
