Overview
The AD5313RBRUZ-RL7, produced by Analog Devices Inc., is a low-power, dual, 10-bit buffered voltage output digital-to-analog converter (DAC) and is part of the nanoDAC® family. This device operates from a single 2.7 V to 5.5 V supply and features a 2.5 V, 2 ppm/°C internal reference. It is guaranteed monotonic by design and exhibits high accuracy with less than 0.1% full-scale range (FSR) gain error and 1.5 mV offset error performance. The AD5313RBRUZ-RL7 is available in a 16-lead TSSOP package and includes a power-on reset circuit and a RSTSEL pin to ensure the DAC outputs power up to zero scale or midscale until a valid write occurs.
