Description

TheAD5623R/AD5643R/ AD5663R, members of thenanoDAC®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.PRODUCT HIGHLIGHTSDual 12-, 14-, and 16-bit DAC.On-chip 1.25 V/2.5 V, 5 ppm/°C reference.Available in 10-lead MSOP and 10-lead, 3 mm × 3 mm LFCSP.Low power; typically consumes 0.6 mW at 3 V and 1.25 mW at 5 V.4.5 μs maximum settling time for the AD5623R.APPLICATIONSProcess controlData acquisition systemsPortable battery-powered instrumentsDigital gain and offset adjustmentProgrammable voltage and current sourcesProgrammable attenuators
