Overview
The AD5663RBRMZ-5, produced by Analog Devices Inc., is a member of the nanoDAC® family. This device is a low-power, dual 16-bit buffered voltage-out digital-to-analog converter (DAC) designed for high precision and low power consumption. It operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5663RBRMZ-5 features an on-chip 2.5 V reference with a temperature coefficient of 5 ppm/°C, providing a full-scale output of 5 V. This DAC is suitable for applications requiring precise digital-to-analog signal transmission and is particularly useful in portable, battery-operated equipment due to its low power consumption.
