GENERAL DESCRIPTION

The AD5620/AD5640/AD5660, members of the nanoDAC™ family of devices, are low power, single, 12-/14-/16-bit, buffered voltage-out DACs and are guaranteed monotonic by design. The AD5620/AD5640/AD5660-1 parts include an internal, 1.25 V, 5 ppm/°C reference, giving a full-scale output voltage range of 2.5 V. The AD5620/AD5640/AD5660-2-3 parts include an internal, 2.5 V, 5 ppm/°C reference, giving a full-scale output voltage range of 5 V. The reference associated with each part is available at the VREFOUT pin.
