The AD5627 members of the nanoDAC^® family are low power, dual, 12-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.

The AD5627 require an external reference voltage to set the output range of the DAC.

The AD5627 incorporate a power-on reset circuit that ensures the DAC output powers up to 0 V, and remains there until a valid write takes place. 

The device contains a per-channel power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode. The low power consumption of this device in normal operation makes it ideally suited to portable battery-operated equipment. The on-chip precision output amplifier enables rail-to-rail output swing.

The AD5627 use a 2-wire I²C-compatible serial interface that operates in standard (100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes.
