Overview
The AD5664RBRMZ-5, 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 reference with options for 1.25 V or 2.5 V references, each with a temperature coefficient of 5 ppm/°C, providing full-scale output ranges of 2.5 V or 5 V, respectively. 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 also includes a per-channel power-down feature to reduce current consumption significantly.
