Overview
The AD5334BRUZ, produced by Analog Devices Inc., is a quad 8-bit digital-to-analog converter (DAC) designed for a wide range of applications requiring precise and efficient analog output. This device operates from a 2.5 V to 5.5 V supply, consuming a low current of 500 μA at 3 V, making it suitable for power-sensitive designs. The AD5334 features a parallel interface and incorporates an on-chip output buffer that enables rail-to-rail voltage output, driving the output to both supply rails.
