The AD5691R/AD5692R/AD5693R, members of the nanoDAC+® family, are low power, single-channel, 12-/14-/16-bit buffered voltage output DACs. The devices include an enabled by default internal 2.5V reference, offering 2ppm/°C drift. The output span can be programmed to be 0 V to VREF or 0 V to 2 x VREF. All devices operate from a single 2.7 to 5.5V supply and are guaranteed monotonic by design. The devices are available in a 2.00 x 2.00mm, 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 contain a power-down mode that reduces the current consumption of the device to 2 ?A (maximum) at 5 V and provides software selectable output loads.
