Working Principles

The ADS7841PG4 is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is sampled and held, and then the internal SAR circuitry compares it to a reference voltage. By iteratively adjusting the digital code, the converter determines the closest digital representation of the analog signal.
