AD5303/AD5313/AD5323  
GENERAꢀ DESCRIPTION  
FEATURES  
AD5303: 2 buffered 8-bit DACs in 1 package  
A version: 1 ꢀSB INꢀ, B version: 0.5 ꢀSB INꢀ  
AD5313: 2 buffered 10-bit DACs in 1 package  
A version: 4 ꢀSB INꢀ, B version: 2 ꢀSB INꢀ  
AD5323: 2 buffered 12-bit DACs in 1 package  
A version: 16 ꢀSB INꢀ, B version: 8 ꢀSB INꢀ  
16-lead TSSOP package  
Micropower operation: 300 μA @ 5 V (including reference  
current)  
Power-down to 200 nA @ 5 V, 50 nA @ 3 V  
2.5 V to 5.5 V power supply  
The AD5303/AD5313/AD5323 are dual 8-/10-/12-bit buffered  
voltage output DACs in a 16-lead TSSOP package that operate  
from a single 2.5 V to 5.5 V supply, consuming 230 μA at 3 V.  
Their on-chip output amplifiers allow the outputs to swing rail-to-  
rail with a slew rate of 0.7 V/μs. The AD5303/AD5313/AD5323  
utilize 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.  
The references for the two DACs are derived from two reference  
pins (one per DAC). These reference inputs may be configured  
as buffered or unbuffered inputs. The parts incorporate a power-  
on reset circuit, which ensures that the DAC outputs power up  
to 0 V and remain there until a valid write to the device takes

place. There is also an asynchronous active low  
clears both DACs to 0 V. The outputs of both DACs may be  
LDAC  
pin that  
updated simultaneously using the asynchronous  
input.  
SDO daisy-chaining option  
The parts contain a power-down feature that reduces the  
current consumption of the devices to 200 nA at 5 V (50 nA  
at 3 V) and provides software-selectable output loads while  
in power-down mode. The parts may also be used in daisy-  
chaining applications using the SDO pin.

ꢀow power serial interface with Schmitt-triggered inputs  
On-chip rail-to-rail output buffer amplifiers  
APPꢀICATIONS  
The low power consumption of these parts in normal operation  
makes them ideally suited to portable battery-operated equip-  
ment. The power consumption is 1.5 mW at 5 V and 0.7 mW at  
3 V, reducing to 1 μW in power-down mode.
