Working Principles

The ADS7253IRTET 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-speed and accurate conversions. The input voltage range can be set according to the reference voltage (VREF) provided externally. The ADC samples the analog input at a specified sampling rate and converts it into a 12-bit digital value. The converted data can then be read through the serial interface (SPI).
