Working Principles

The 8N3DV85BC-0104CDI8 is a digital-to-analog converter that operates based on the principle of binary-weighted resistor networks. It receives digital input data through the DIN pin and converts it into an analog voltage output at the VOUT pin. The conversion process involves using a reference voltage (provided through the REF pin) and a series of resistors with different values. By selectively activating these resistors according to the digital input, the DAC generates an accurate analog voltage proportional to the input code.
