GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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.  
1. 18 bits of resolution.  
2. 12-bit accuracy guaranteed for 18-bit DAC.  
3. Available in an 8-lead SOT-23.  
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.  
4. Low power. Typically consumes 1.6 mW at 5 V.  
5. Power-on reset to zero scale or to midscale.  
RELATED DEVICES  
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.  
AD5662 16-bit DAC in SOT-23.  
The AD5680 on-chip precision output amplifier allows rail-to-  
rail output swing to be achieved. For remote sensing applications,  
the output amplifiers 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.
