Working Principles

The MX7547LN is a digital-to-analog converter that converts binary digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high precision conversion. The input digital data is processed internally and converted into an analog voltage proportional to the input value. The on-chip reference voltage generator ensures accurate conversion by providing a stable reference voltage. The output voltage range is determined by the reference voltage (Vref) provided externally.
