Working Principles

The MAX693CWE+T is a digital-to-analog converter (DAC) that converts digital signals into analog voltage or current. It utilizes a 12-bit resolution to provide high accuracy and precision in generating analog signals. The device operates with a supply voltage ranging from 2.7V to 5.5V and can be controlled through a serial interface using the chip select input, serial data input, and serial clock input.

The DAC's output can be configured as either voltage or current mode, with a selectable output range. In voltage mode, the output voltage ranges from 0V to the reference voltage (Vref). In current mode, the output current ranges from 4mA to 20mA. The reference voltage can be provided externally or generated internally.
