GENERAL DESCRIPTION
The AD5693R/AD5692R/AD5691R/AD5693, members of the
nanoDAC+® 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
VREF or 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 asynchronous
RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.
