The AD5683R/AD5682R/AD5681R/AD5683, members of thenanoDAC+® family, are low power, single-channel, 16-/14-/12-bitbuffered voltage out digital-to-analog converters (DACs). Thedevices, except the AD5683, include an enabled by default internal2.5 V reference, offering 2 ppm/°C drift. The output span can beprogrammed to be 0 V to VREF or 0 V to 2 × VREF. All devicesoperate from a single 2.7 V to 5.5 V supply and are guaranteedmonotonic 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 registeris written to zero scale at power-up while the internal outputbuffer is configured in normal mode. TheAD5683R/AD5682R/AD5681R/AD5683 contain a power-downmode that reduces the current consumption of the device to 2 µA(maximum) at 5 V and provides software selectable output loadswhile in power-down mode.
The AD5683R/AD5682R/AD5681R/AD5683 use a versatile3-wire serial interface that operates at clock rates of up to 50 MHz.Some devices also include asynchronous RESET pin and VLOGICpin options, allowing 1.8 V compatibility
