Overview
The AD5692RACPZ-RL7, produced by Analog Devices Inc., is a member of the nanoDAC+® family. This device is a low-power, single-channel, 14-bit buffered voltage output digital-to-analog converter (DAC). It is designed to offer high accuracy and low drift, making it suitable for a variety of applications requiring precise voltage output.
The AD5692RACPZ-RL7 operates from a single 2.7 V to 5.5 V supply and features an internal 2.5 V reference with a low temperature coefficient of 2 ppm/°C typical. The device is available in a compact 2 mm × 2 mm, 8-lead LFCSP package and is compatible with 1.8 V logic.
