Working Principles

The MAX396EWI is a digital-to-analog converter that converts digital signals into corresponding analog voltage levels. It utilizes a 16-bit resolution to provide high accuracy in the conversion process. The input digital data is received through the serial data input (DIN) pin, synchronized by the serial clock input (SCLK), and updated simultaneously on the analog outputs. The reference voltage (VREF) determines the maximum output voltage, which can be adjusted within a specified range. The DAC operates within a wide supply voltage range and consumes minimal power, making it suitable for various applications.
