Working Principles

The AD7545ALNZ is a digital-to-analog converter (DAC) that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high accuracy in the conversion process. The digital input bits (DB11-DB0) determine the desired analog output voltage, which is then generated at the OUT pin. The WR and CS control inputs, along with the address inputs (A2-A0), facilitate the selection and writing of data to the DAC.
