The AD5697R, a member of the nanoDAC+™ family, is a low power,dual, 12-bit buffered voltage output digital-to-analog converter(DAC). The device includes a 2.5 V, 2 ppm/°C internal reference(enabled by default) and a gain select pin giving a full-scale outputof 2.5 V (gain = 1) or 5 V (gain = 2). The AD5697R operates froma single 2.7 V to 5.5 V supply, is guaranteed monotonic by design,and exhibits less than 0.1% FSR gain error and 1.5 mV offseterror performance. The device is available in a 3 mm × 3 mmLFCSP and a TSSOP package.

The AD5697R also incorporates a power-on reset circuit and aRSTSEL pin that ensure that the DAC outputs power up to zeroscale or midscale and remain there until a valid write takesplace. It contains a per channel power-down feature that reducesthe current consumption of the device to 4 µA at 3 V while inpower-down mode.

The AD5697R uses a versatile 2-wire serial interface that operatesat clock rates up to 400 kHz and includes a VLOGIC pin intendedfor 1.8 V/3 V/5 V logic.
