2.7 V to 5.5 V quad, 12-, 14-,
16-bit DACs with internal
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
