Overview
The AD5664RBRMZ-5REEL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low-power, quad, 16-bit buffered voltage-out digital-to-analog converter (DAC). This device operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5664R features an on-chip 2.5 V, 5 ppm/°C reference, which can be enabled via a software write, and it also supports the use of an external reference. The device 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. It is particularly suited for portable battery-operated equipment due to its low power consumption.
