Analog Devices Inc. AD5683R/AD5682R/AD5681R/AD5683 nanoDAC+

Analog Devices Inc. AD5683R/AD5682R/AD5681R/AD5683 nanoDAC+ are part of the nanoDAC+® family of low power, single-channel, 16-/14-/12-bit buffered voltage out DACs. 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 2μA (maximum) at 5V and provides software selectable output loads while in power-down mode. The devices, except the AD5683, include an enabled by default internal 2.5V reference, offering 2 ppm/°C drift. The output span can be programmed to be 0V to VREF or 0V to 2 × VREF. All devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. The devices are available in a 2.00mm × 2.00 mm, 8-lead LFCSP or a 10-lead MSOP.
