Dual 14-Bit nanoDAC® With 5 Ppm/°C On-Chip Reference

The AD5623R AD5643R AD5663R members of the nanoDAC family, are low power, dual 12-, 14-, and 16-bit buffered voltage- out digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design.
The AD5623R AD5643R AD5663R have an on-chip reference. The AD5623R-3/AD5643R-3/AD5663R-3 have a 1.25 V, 5 ppm/C reference, giving a full-scale output of 2.5 V; and the AD5623R-5/ AD5643R-5/AD5663R-5 have a 2.5 V, 5 ppm/C reference, giving a full-scale output 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 turned on by writing to the DAC
The parts 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 part contains a 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 AD5623R AD5643R AD5663R use a versatile, 3-wire serial Interface that operates at Clock rates up to 50 MHz, and they are compatible with standard SPI, QSPI, MICROWIRE, and DSP Interface standards. The on-chip precision output Amplifier enables Rail-to-Rail output swing to be achieved.
