Working Principles

The AD5302ARMZ is a digital-to-analog converter that converts digital signals into analog voltages. It utilizes a 12-bit resolution to provide high precision and accuracy in the generated analog output. The device operates using a serial peripheral interface (SPI), allowing easy integration with microcontrollers.

The DAC has two output channels, AOUT1 and AOUT2, which can generate simultaneous analog voltages based on the digital input received through the DIN pin. The reference voltage, VREF, sets the maximum output voltage range from 0V to VREF.

The AD5302ARMZ also features a power-on reset circuit that ensures reliable startup behavior. Its low glitch energy minimizes disturbances in the output voltage during transitions.
