TheAD5693R/AD5692R/ AD5691R /AD5693, members of thenanoDAC+®family, are low power, single-channel, 16-/14-/12-bit buffered voltage output DACs. The devices, except the AD5693, 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 AD5693R / AD5692R / AD5691R / AD5693 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.The AD5693R / AD5692R / AD5691R / AD5693 use an I2C interface. Some device options also include an asynchronousRESETpin and a VLOGICpin, allowing 1.8 V compatibility.Product HighlightsHigh relative accuracy (INL): ±2 LSB maximum (AD5693R/AD5693, 16-bit).Low drift, 2.5 V on-chip reference: 2 ppm/°C typical and 5 ppm/°C maximum temperature coefficient.2 mm × 2 mm, 8-lead LFCSP and 10-lead MSOP.ApplicationsProcess controlsData acquisition systemsDigital gain and offset adjustmentProgrammable voltage sourcesOptical modules
