Working Principles

The AD7542KN is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide precise output voltage levels. The input digital data is received through the DB0-DB11 pins, and the WR (Write), CS (Chip Select), RD (Read), and CLK (Clock) pins control the conversion process. The Vref pin provides the reference voltage against which the digital inputs are converted.
