GENERAL DESCRIPTION

The AD5627R/AD5647R/AD5667R, AD5627/AD5667 members of the nanoDAC family are low power, dual, 12-, 14-, 16-bit buffered voltage-out DACs with/without on-chip reference. All devices operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and have an I2C compatible serial interface.
