GENERAL DESCRIPTION  
all DACs can be updated simultaneously using the  
function, with the added functionality of user-selectable DAC  
channels to simultaneously update. There is also an  
LDAC  
The AD5025/45/65 are low power, dual 12-/14-/16-bit buffered  
voltage-out DACs offering relative accuracy specs of 1 LSB INL  
with individual reference pins and can operate from a single 2.7  
V to 5.5 V supply. The AD5025/45/65 64 parts also offer a  
differential accuracy specification of 1 LSB. The parts use a  
versatile 3-wire, low power Schmitt trigger serial interface that  
operates at clock rates up to 50 MHz and is compatible with  
standard SPI®, QSPI™, MICROWIRE™, and DSP interface  
standards. The reference for the AD5025/45 and AD5065 are  
supplied from an external pin. A reference buffer is also  
provided on-chip. The AD5025/45/64 incorporates a power-on  
reset circuit that ensures the DAC output powers up zero scale  
or midscale and remains there until a valid write takes place to  
the device. The AD5025/45/65 contain a power-down feature  
that reduces the current consumption of the device to typically  
330 nA at 5 V and provides software selectable output loads  
while in power-down mode. The parts are put into power-down  
mode over the serial interface. Total unadjusted error for the  
parts is <2 mV.

code—0 V, midscale, or full scale. The Part also features a power  
down lockout pin , which can be used to prevent the DAC  
PDL  
from entering power down under any circumstances over the  
serial interface.  
PRODUCT HIGHLIGHTS  
1. Dual channel available in 14-lead TSSOP package with  
individual Voltage reference pins.  
2. 12-/14-/-16 bit accurate, 1 LSB INL.  
3. Low glitch on power-up.  
4. High speed serial interface with clock speeds up to 50 MHz.  
5. Three power-down modes available to the user.  
6. Reset to known output voltage (zero scale or midscale).  
7. Power Down lockout capability.  
Both parts exhibit very low glitch on power-up. The outputs of
