Working Principles

The TLV2548CDWG4 is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It achieves this by sampling the input voltage at regular intervals and quantizing it into a binary code. The ADC's resolution determines the number of possible output codes, with a 12-bit resolution providing 4096 distinct levels.

The device operates by comparing the input voltage with a reference voltage (Vref) and generating a digital code proportional to the input voltage. This digital code is then transmitted through the SPI interface to a microcontroller or other digital circuitry for further processing.
