Overview
The AD5693RBRMZ, produced by Analog Devices Inc., is a member of the nanoDAC+® family. It is a low-power, single-channel, 16-bit buffered voltage output Digital-to-Analog Converter (DAC). This device is designed for high accuracy and low drift, making it suitable for a variety of precision applications. The AD5693RBRMZ operates from a single 2.7 V to 5.5 V supply and features an internal 2.5 V reference with a drift of 2 ppm/°C typical. The device is available in a compact 10-lead MSOP package and supports an I2C interface for communication.
