Overview
The AD5663RBCPZ-3R2, produced by Analog Devices Inc., is a member of the nanoDAC family. It is a low-power, dual 16-bit buffered voltage-out digital-to-analog converter (DAC) designed for high precision and reliability. This device operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5663RBCPZ-3R2 features an on-chip 1.25 V, 5 ppm/°C reference, providing a full-scale output of 2.5 V. It includes a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. This component is ideal for applications requiring low power consumption, such as portable, battery-operated equipment.
