FEATURES  
DESCRIPTION  
TheLTC®1450/LTC1450Larecompletesinglesupply,rail-  
to-rail voltage output, 12-bit digital-to-analog converters  
(DACs)ina24-pinSSOPorPDIPpackage.Theyincludean  
output buffer amplifier, reference and a double buffered  
parallel digital interface.  
12-Bit Resolution  
3V Operation (LTC1450L) ICC: 250µA Typ  
5V Operation (LTC1450) ICC: 400µA Typ  
Parallel 12-Bit or 8 + 4-Bit Double Buffered  
The LTC1450 operates from a 4.5V to 5.5V supply. The  
outputcanbepinstrappedfor4.095Vor2.048Vfull-scale.  
It has a 2.048V internal reference.  
Digital Input  
Internal Reference  
Output Buffer Configurable to Gain of 1 or 2  
Configurable as a Multiplying DAC  
Internal Power-On Reset  
The LTC1450L operates from a 2.7V to 5.5V supply. The  
output can be pin strapped for 2.5V or 1.22V full-scale. It  
has a 1.22V internal reference.  
U
The LTC1450/LTC1450L offer true stand-alone perfor-  
mance. In addition, the reference output, high and low  
reference inputs and gain setting resistor are brought to  
pins for maximum flexibility.
