Overview
The AD5627BRMZ is a member of the nanoDAC family from Analog Devices Inc., designed as a low-power, dual 12-bit buffered voltage-out digital-to-analog converter (DAC). This device is part of a series that includes 12-, 14-, and 16-bit versions, all of which are known for their high precision and low power consumption. The AD5627BRMZ operates from a single 2.7 V to 5.5 V supply and features an I2C-compatible serial interface that supports standard, fast, and high-speed modes. It is particularly suited for applications requiring high accuracy and low power, such as process control, data acquisition systems, and portable battery-powered instruments.
