GENERAL DESCRIPTION
The AD5338R, a member of the nanoDAC® family, is a low power, dual, 10-bit buffered voltage output digital-to-analog converter (DAC). The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The AD5338R operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.
