The datasheet does not indicate an operating supply voltage of -0.5 to +15v, those are the absolute maximum ratings.
Use the part within it's recommended ratings of 10.8 to 13.2 volts and you won't have any issues. Otherwise, all bets are off. It never ceases to amaze me when people use a part outside it's spec and then wonder why they have problems. Would you use a lawnmower to trim your hedge? Your weed whip to cut down a tree?
