TheAD5683R/AD5682R/AD5681R/AD5683, members of thenanoDAC+®family, are low power, single-channel, 16-/14-/12-bit buffered voltage out digital-to-analog converters (DACs). The devices, except the AD5683, include an enabled by default internal 2.5 V reference, offering 2 ppm/°C drift. The output span can be programmed to be 0 V to VREFor 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in a 2.00 mm × 2.00 mm, 8-lead LFCSP or a 10-lead MSOP.The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5683R/AD5682R/AD5681R/AD5683 contain a power-down mode that reduces the current consumption of the device to 2 µA (maximum) at 5 V and provides software selectable output loads while in power-down mode.The AD5683R/AD5682R/AD5681R/AD5683 use a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz. Some devices also include asynchronousRESETpin and VLOGICpin options, allowing 1.8 V compatibilityProduct HighlightsHigh Relative Accuracy (INL).AD5683R/AD5683 (16-bit): ±2 LSB maximum.Low Drift, 2.5 V On-Chip Reference.2 ppm/°C typical temperature coefficient.5 ppm/°C maximum temperature coefficient.Two Package Options.2.00 mm × 2.00 mm, 8-lead LFCSP.10-lead MSOP.ApplicationsProcess controlsData acquisition systemsDigital gain and offset adjustmentProgrammable voltage sources
