Working Principles

The DAC7545GLURG4 operates by accepting a digital input signal and converting it into a corresponding analog voltage. It utilizes a 12-bit digital-to-analog conversion technique, where the digital input is divided into 4096 discrete levels. These levels are then converted into proportional analog voltages within the specified voltage output range.

The DAC7545GLURG4 requires a stable voltage reference (Vref) to determine the maximum analog output voltage. The digital input is provided through serial communication using the CS (Chip Select), SCLK (Serial Clock), and SDIN (Serial Data Input) pins. The selected digital value is converted into an analog voltage, which appears at the Vout pin.
