AD5313R Series

The AD5313R, a member of thenanoDAC®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 AD5313R 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 package and a TSSOP package.The AD5313R also incorporates a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write occurs. The part contains a per channel power-down feature that reduces the current consumption of the device to 4 μA at 3 V while in power-down modeThe AD5313R employs a versatile serial peripheral interface (SPI) that operates at clock rates up to 50 MHz, and the device contains a VLOGICpin that is intended for 1.8 V/3 V/5 V logic.Product HighlightsPrecision DC Performance.Total unadjusted error: ±0.1% of FSR maximumOffset error: ±1.5 mV maximumGain error: ±0.1% of FSR maximumLow Drift 2.5 V On-Chip Reference.2 ppm/°C typical temperature coefficient5 ppm/°C maximum temperature coefficientTwo Package Options.3 mm × 3 mm, 16-lead LFCSP16-lead TSSOPApplicationsOptical transceiversBase station power amplifiersProcess control (PLC I/O cards)Industrial automationData acquisition systems
