Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 2: All voltages are with respect to GND.  
Note 3: High temperatures degrade operating lifetimes. Operating lifetime  
Note 5: Inferred from measurement at code 16 (LTC2636-12), code 4  
(LTC2636-10) or code 1 (LTC2636-8), and at full-scale.  
Note 6: This IC includes current limiting that is intended to protect the  
device during momentary overload conditions. Junction temperature can  
exceed the rated maximum during current limiting. Continuous operation  
above the specified maximum operating junction temperature may impair  
device reliability.
