The AD5680, a member of the nanoDAC family, is a single,
18-bit buffered voltage-out DAC that operates from a single
4.5 V to 5.5 V supply and is 18-bit monotonic.
The AD5680 requires 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
(AD5680-1) or to midscale (AD5680-2) and remains there until
a valid write takes place.
The low power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment.
The power consumption is 1.6 mW at 5 V.
The AD5680 on-chip precision output amplifier allows rail-to-
rail output swing to be achieved. For remote sensing applications,
the output amplifier’s inverting input is available to the user.
The AD5680 uses a versatile 3-wire serial interface that operates
at clock rates up to 30 MHz, and is compatible with standard
SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
