I have a bag of DAC7512N digital to analog converter from TI. They are still sealed in the original packing, however the caution notes denote "calculated shelf life in sealed bag: 24 months" and the sealed date on the packing dates back to 01/01/07. Now the question is the shelf life an absolute lifetime for the devices in other words after the 24 months are the component unusable? or does it mean that at this point further procedures must be applied to the component such as baking before they could be used in a circuit?
