Working Principles

The ADS7953SDBTG4 operates by sampling the analog input voltage and converting it into a digital representation using its internal circuitry. The analog signal is first amplified and then passed through a sample-and-hold circuit. The sampled voltage is then quantized into discrete levels using a successive approximation register (SAR) algorithm. Finally, the digital output is transmitted through the SPI interface for further processing or analysis.
