Working Principles

ADS1192IRSMT operates by receiving analog bio-potential signals through the AINP and AINN pins. These signals are then amplified using the built-in PGA and filtered to reduce noise interference. The analog-to-digital converter (ADC) converts the filtered signals into digital data, which can be accessed through the serial interface. The device is controlled using various control inputs such as CLK, CS, START, PWDN, and RESET.
