Overview
The AD5683RACPZ-1RL7, produced by Analog Devices Inc., is a member of the nanoDAC+® family. It is a low-power, single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC). This device features an internal 2.5 V reference with a drift of 2 ppm/°C, which is enabled by default. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. The AD5683R operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It is available in an 8-lead LFCSP package, measuring 2.00 mm × 2.00 mm, and is RoHS compliant.
