Working Principles

The DAC8426FSZ-REEL utilizes a digital-to-analog conversion technique called pulse-width modulation (PWM). It converts the incoming digital data into a corresponding analog voltage by rapidly switching between two voltage levels. The ratio of the on-time to the total switching period determines the average output voltage.

The digital input data is received through the serial interface (SPI) and processed internally to generate the desired analog output voltage. The internal reference voltage generator ensures accurate conversion by providing a stable reference voltage.
