Working Principles

The X9438WV24I is a digital-to-analog converter (DAC) IC that converts digital signals into corresponding analog voltages. It utilizes a 12-bit resolution to provide accurate and precise analog outputs. The IC operates with a supply voltage of 3.3V and communicates with external devices through the Serial Peripheral Interface (SPI).

When a digital value is received via the SPI interface, the X9438WV24I internally converts it into an analog voltage within the specified output voltage range. The converted analog voltage is then available at the VOUT pin for further processing or utilization in the application.
