Working Principles

The MAX13055EETI+T operates by converting analog input voltages into digital representations using a 16-bit successive approximation register (SAR) ADC. The input voltage is amplified by the integrated PGA, which can be programmed to adjust the gain according to the application requirements. The on-chip temperature sensor provides accurate temperature measurements, allowing for compensation or monitoring purposes.

The IC communicates with external devices through the SPI interface, utilizing a serial clock (SCLK) and serial data (SDATA) lines. The chip select (CS) input is used to enable or disable the device. The data ready (DRDY) output signal indicates when a new conversion result is available for retrieval.
