Working Principles

The DAC0802LCM/NOPB operates by converting digital input signals into corresponding analog voltage outputs. It utilizes an internal reference voltage (Vref) and a digital-to-analog conversion technique to generate the desired analog output voltage. The digital input signals control the binary-weighted current sources, which are then converted into an analog voltage through a resistor ladder network. The resulting analog voltage is available at the OUT pin.
