Working Principles

The LTC2215CUP#PBF operates based on the principle of analog-to-digital conversion. It takes an analog input signal, provided through the VIN+ and VIN- pins, and converts it into a digital representation using an internal ADC core. The converted digital data is then available at the DOUT pin for further processing or storage.

The ADC utilizes a clock signal (CLK) to synchronize the conversion process. The chip select (CS) pin is used to initiate the conversion and control the device's operation. The reference voltages (VREF+ and VREF-) determine the ADC's dynamic range and resolution.
