Part No. AD5624R/AD5644R/AD5664R Description 2.7 V to 5.5 V quad, 12-, 14-, 16-bit DACs with internal reference
GENERAL DESCRIPTION
The AD5624/AD5664, members of the nanoDAC family, are low power, quad, 12-, 16-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5624/AD5664 require an external reference voltage to set the output range of the DAC. The part incorporates a poweron reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The parts contai...
