Overview
The AD5667RBRMZ-1 is a dual, 16-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, small footprint, and high precision. It operates from a single 2.7 V to 5.5 V supply and features an I2C-compatible serial interface. The AD5667RBRMZ-1 includes an on-chip 2.5 V, 5 ppm/°C reference, which provides a full-scale output range of 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 until a valid write takes place.
