Working Principles

The ADS7960QDBTRQ1 operates based on the successive approximation register (SAR) architecture. It converts analog signals into digital data by comparing the input voltage with a reference voltage and iteratively determining the most significant bits (MSBs) and least significant bits (LSBs) of the digital output.

The internal circuitry of the ADC includes a sample-and-hold amplifier, a SAR ADC core, and a digital interface. The sample-and-hold amplifier captures and holds the input voltage during the conversion process. The SAR ADC
