GENERAL DESCRIPTION
The AD5680, a member of the nanoDAC family, is a single,
18-bit buffered voltage-out digital-to-analog converter (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.
PRODUCT HIGHLIGHTS
1. 18 bits of resolution.
2. 12-bit accuracy guaranteed for 18-bit DAC.
3. Available in an 8-lead SOT-23.
4. Low power; typically consumes 1.6 mW at 5 V.
5. Power-on reset to zero scale or to midscale.
