Working Principles

The MAX5443ACUA operates by converting digital input signals into corresponding analog voltages. It utilizes a 12-bit resolution DAC to accurately represent the digital data as an analog output voltage. The chip select input (CS) and serial clock input (SCLK) control the data transfer, while the digital input (DIN) receives the digital data. The reference voltage (VREF) determines the maximum output voltage range.
