Overview
The AD5627RBCPZ-REEL7 is a dual, 12-bit nanoDAC (digital-to-analog converter) produced by Analog Devices Inc. This device is part of the nanoDAC family and is known for its low power consumption and compact design. It operates from a single 2.7 V to 5.5 V supply and features an I2C-compatible serial interface. The AD5627RBCPZ-REEL7 includes an on-chip 1.25 V reference with a 5 ppm/°C temperature coefficient, providing a full-scale output range of 2.5 V. The device is guaranteed monotonic by design and includes a power-on reset circuit that ensures the DAC output powers up to 0 V.
