AD5664 2.7 V to 5.5 V, 450 µA, Rail-to-Rail Output, Quad, 16-Bit nanoDAC®

Relative accuracy: ±12 LSBs maximum. Available in 10-lead MSOP and 10-lead, 3 mm × 3 mm, LFCSP_WD. Low power, typically consumes 1.32 mW at 3 V and 2.25 mW at 5 V. Maximum settling time of 4.5 μs (AD5624) and 7 μs (AD5664). Applications

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 power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The parts contain 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 these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 2.25 mW at 5 V, going down to 2.4 μW in power-down mode.

The AD5624/AD5664 on-chip precision output amplifier allows rail-to-rail output swing to be achieved.The AD5624/AD5664 use a versatile 3-wire serial interface that operates at clock rates up to 50 MHz, and are compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
