AD5643R:  Dual 14-Bit nanoDAC® with 5 ppm/°C On-Chip Reference

Product Details


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.
