Overview
The AD5627BRMZ-REEL7 is a member of the nanoDAC family from Analog Devices Inc., offering a low-power, dual 12-bit buffered voltage-out digital-to-analog converter (DAC). This device is part of the AD5627R/AD5647R/AD5667R and AD5627/AD5667 series, known for their high precision and low power consumption. It 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. The device is guaranteed monotonic by design and includes a power-on reset circuit that ensures the DAC output powers up to 0 V until a valid write takes place.
