Working Principles

The DAC8565IBPW operates by converting digital input signals into corresponding analog voltages. It utilizes a 16-bit digital word to represent the desired output voltage level. The device employs an internal digital-to-analog conversion technique that accurately converts the digital data into analog voltages.

The DAC receives digital input data through the SPI interface, processes it internally, and generates the corresponding analog output voltages on the four output channels (OUTA, OUTB, OUTC, and OUTD). The settling time of the DAC ensures that the output voltage reaches its desired level quickly and accurately.
