Overview
The AD5684RBRUZ, part of the nanoDAC+ family from Analog Devices Inc., is a low-power, quad, 12-bit buffered voltage output digital-to-analog converter (DAC). This device is designed for high precision and reliability, operating from a single supply voltage ranging from 2.7 V to 5.5 V. It features a 2.5 V, 2 ppm/°C internal reference and a gain select pin, allowing for full-scale outputs of 2.5 V or 5 V. The AD5684RBRUZ is available in compact 3 mm x 3 mm LFCSP and TSSOP packages, making it ideal for space-saving designs.
