Quad, 14-Bit nanoDAC® With 5ppm/°C On-Chip Reference

The AD5624R AD5644R AD5664R members of the nanoDAC family, are low power, quad, 12-/14-/16-bit buffered voltage-out DACs All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design.
The AD5624R AD5644R AD5664R have an on-chip reference. The AD56x4R-3 has a 1.25 V, 5 ppm/C reference, giving a full-scale output range of 2.5 V; the AD56x4R-5 has a 2.5 V, 5 ppm/C reference giving a full-scale output range of 5 V. The on-chip reference is off at power-up allowing the use of an external reference and all devices CAN be operated from a single 2.7 V to 5.5 V supply. The internal reference is enabled via a software write.
The part incorporates 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 part 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 part in normal operation makes it ideally suited to portable battery-operated equipment.
The AD5624R AD5644R AD5664R use a versatile 3-wire serial Interface that operates at Clock rates up to 50 MHz, and is compatible with standard SPI, QSPI, MICROWIRE, and DSP Interface standards. The on-chip precision output Amplifier enables Rail-to-Rail output swing.
