GENERAꢀ DESCRIPTION  
The AD5306/AD5316/AD53261 are quad 8-/10-/12-bit buffered  
voltage output DACs in 16-lead TSSOP packages that operate  
from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V.  
Their on-chip output amplifiers allow rail-to-rail output swing  
with a slew rate of 0.7 V/μs. A 2-wire serial interface, which  
operates at clock rates up to 400 kHz, is used. This interface is  
SMBus-compatible at VDD < 3.6 V. Multiple devices can be  
placed on the same bus.  
On-chip rail-to-rail output buffer amplifiers  
Temperature range −40°C to +105°C  
APPꢀICATIONS  
Portable battery-powered instruments  
Digital gain and offset adjustment  
Programmable voltage and current sources  
Programmable attenuators  
Each DAC has a separate reference input that can be configured  
as buffered or unbuffered. The outputs of all DACs can be  
Industrial process control  
updated simultaneously using the asynchronous  
input.  
LDAC  
The parts incorporate a power-on reset circuit that ensures the  
DAC outputs power up to 0 V and remain there until a valid  
write to the device takes place. The software clear function  
clears all DACs to 0 V. The parts contain a power-down feature  
that reduces the current consumption of the device to  
300 nA @ 5 V (90 nA @ 3 V).  
All three parts have the same pinout, which allows users to select  
the amount of resolution appropriate for their application without  
redesigning their circuit board.
