Working Principles

The AD5543BR utilizes a digital-to-analog conversion technique called pulse width modulation (PWM). It converts the digital input data into a corresponding analog output voltage or current by adjusting the width of pulses. The internal reference voltage sets the maximum output level, and the digital input determines the pulse width.
