Overview
The AD5696BRUZ, produced by Analog Devices Inc., is a member of the nanoDAC+™ family. It is a low power, quad, 16-bit buffered voltage output digital-to-analog converter (DAC). This device is designed for high accuracy and low power consumption, making it suitable for a variety of applications requiring precise analog output.
The AD5696 operates from a single supply voltage of 2.7 V to 5.5 V and features a versatile 2-wire serial interface with clock rates up to 400 kHz. It includes a gain select pin, allowing for a full-scale output of 0 V to VREF (gain = 1) or 0 V to 2VREF (gain = 2). The device is available in both 3 mm × 3 mm LFCSP and 16-TSSOP packages.
