Precision Buffered  
Reference Family  
FeaTures  
DescripTion  
The LTC®6655 is a complete family of precision bandgap  
voltage references, offering exceptional noise and drift  
performance. This low noise and drift is ideally suited for  
thehighresolutionmeasurementsrequiredbyinstrumenta-  
tion and test equipment. In addition, the LTC6655 is fully  
specified over the temperature range of –40°C to 125°C,  
ensuring its suitability for demanding automotive and  
industrialapplications.Advancedcurvaturecompensation  
allowsthisbandgapreferencetoachieveadriftoflessthan  
2ppm/°C with a predictable temperature characteristic  
and an output voltage accurate to 0.025ꢀ, reducing or  
eliminating the need for calibration.

3.3V, 4.096V, 5V  
Available in an 8-Lead MSOP Package  
The LTC6655 can be powered from as little as 500mV  
above the output voltage to as much as 13.2V. Superior  
load regulation with source and sink capability, coupled  
with exceptional line rejection, ensures consistent per-  
formance over a wide range of operating conditions. A  
shutdown mode is provided for low power applications.  
Available in a small MSOP package, the LTC6655 family  
of references is an excellent choice for demanding preci-  
sion applications.
