Working Principles

The MAX5441ACUA is a digital-to-analog converter that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide high precision output. The device operates within a specified supply voltage range and generates analog voltages between 0V and the reference voltage (VREF). The digital input data is received through the serial interface and converted into an analog output voltage. The load DAC input allows for simultaneous updates of multiple DACs, enabling synchronized analog voltage generation.
