Working Principles

The AD569JPZ is a digital-to-analog converter that utilizes a 16-bit binary input to generate an analog output voltage. It employs a resistor ladder network and internal circuitry to convert the digital input code into a corresponding analog voltage. The reference voltage (VREF) determines the maximum output voltage, which can be adjusted within the specified range. The digital inputs control the switching of resistors in the ladder network, resulting in the desired analog output voltage.
