Working Principles

The 8N3DV85KC-0204CDI8 is a digital-to-analog converter (DAC) that converts digital signals into analog signals. It operates by taking a digital input signal and converting it into an equivalent analog voltage output. The resolution of the DAC determines the number of discrete voltage levels that can be represented, with this model offering a 12-bit resolution.

The DAC utilizes an internal or external reference voltage to establish the output range. The digital input signal is received through a serial peripheral interface (SPI), which allows for easy communication with microcontrollers. The converted analog signal is then available at the OUTA and OUTB pins.
