Working Principles

The AD5620CRM-2 operates based on the principle of digital-to-analog conversion. It accepts digital input data through the serial interface and converts it into an analog voltage output. The resolution of 12 bits allows for a wide range of output voltage levels, providing fine-grained control over the analog signal.

The DAC utilizes an internal reference voltage (Vref) or an externally provided reference voltage to determine the output voltage level. The digital input data is processed using a digital-to-analog conversion algorithm, which generates the corresponding analog voltage. This analog voltage can then be used as a control signal or fed into other analog circuits for further processing.
