Working Principles

The PT8A978BPE is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a 12-bit resolution to provide high accuracy in converting the input voltage into its corresponding digital representation. The ADC operates by sampling the analog input voltage at a specified rate, and then quantizing it into a digital value using an internal reference voltage. The converted digital data can be accessed through the serial data output pin.
