FEATURES  
DESCRIPTION  
The LT®1634 is a micropower, precision, shunt voltage  
reference. The bandgap reference uses trimmed precision  
thin film resistors to achieve 0.05% initial voltage accu-  
racy. Improved curvature correction technique guaran-  
tees 10ppm/°C maximum temperature drift. Advances in  
design, processing and packaging techniques guarantee  
10µA operation and low temperature cycling hysteresis.  
The LT1634 does not require an output compensation  
capacitor,butisstablewithcapacitiveloads.Lowdynamic  
impedance makes the LT1634 reference easy to use from  
unregulated supplies.  
Initial Voltage Accuracy: 0.05%  
Low Operating Current: 10µA  
Low Drift: 10ppm/°C Max  
Less Than 1Dynamic Impedance  
Available in 1.25V, 2.5V, 4.096V and 5V in SO-8  
and TO-92 Packages  
1.25V and 2.5V Available in MSOP Package  
Both Commercial and Industrial Temperature Range  
Parts Are Available
