GENERAL DESCRIPTION  
The AD5624R/AD5644R/AD5664R, members of the nanoDAC  
family, are low power, quad, 12-/14-/16-bit buffered voltage-out  
DACs. All devices operate from a single 2.7 V to 5.5 V supply  
and are guaranteed monotonic by design.  
while in power-down mode. The low power consumption of  
this part in normal operation makes it ideally suited to portable  
battery-operated equipment.  
The AD5624R/AD5644R/AD5664R use a versatile 3-wire serial  
interface that operates at clock rates up to 50 MHz, and is  
compatible with standard SPI®, QSPI™, MICROWIRE™, and  
DSP interface standards. The on-chip precision output amplifier  
enables rail-to-rail output swing.  
The AD5624R/AD5644R/AD5664R have an on-chip reference.  
The AD56x4R-3 has a 1.25 V, 5 ppm/°C reference, giving a full-  
scale output range of 2.5 V; the AD56x4R-5 has a 2.5 V,  
5 ppm/°C reference giving a full-scale output range of 5 V. The  
on-chip reference is off at power-up allowing the use of an  
external reference and all devices can be operated from a single  
2.7 V to 5.5 V supply. The internal reference is enabled via a  
software write.  
PRODUCT HIGHLIGHTS  
1. Quad 12-/14-/16-bit DACs.  
2. On-chip 1.25 V/2.5 V, 5 ppm/°C reference.  
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 part contains a per-channel power-down  
feature that reduces the current consumption of the device to  
480 nA at 5 V and provides software-selectable output loads  
3. Available in 10-lead MSOP and 10-lead, 3 mm × 3 mm,  
LFCSP_WD.  
4. Low power, typically consumes 1.32 mW at 3 V and  
2.25 mW at 5 V.
