Working Principles

The DAC8420FSZ operates based on the principle of converting digital input data into corresponding analog output voltages. It utilizes a combination of digital circuitry and precision analog components to achieve accurate conversion.

When digital data is applied to the input pins (D11-D0), the DAC8420FSZ internally processes this data and generates an analog output voltage proportional to the input value. The reference voltage (VREF) determines the maximum analog output voltage, which can be adjusted according to the application requirements.

The conversion process is controlled by the chip select (CS) input and the clock signals (SCLK and SDIN for serial interface). Upon receiving the digital input data, the DAC8420FSZ performs the necessary calculations and produces the corresponding analog output on the AOUT pin.
