Working Principles

The DAC8551IDGKT operates by converting digital input signals into corresponding analog output voltages. It utilizes a 16-bit digital word to determine the output voltage level. The input digital data is received through the DIN pin and synchronized with the serial clock (SCLK) signal. The chip select (CS) pin enables the DAC for data transfer. Once the digital data is received, the DAC performs a conversion and generates the corresponding analog voltage at the VOUT pin.
