Working Principles

ADS1243IPWR operates by converting analog signals into digital data using a successive approximation register (SAR) architecture. The analog input is amplified and conditioned by the integrated programmable gain amplifier before being converted into a digital representation. The conversion process is controlled by an internal clock and can be triggered by an external signal. The resulting digital data is then available for further processing or transmission.
