I've been trying to identify this little fellow:

The symbol indicates Analog devices. But the Cryptic "Y 4 A" is giving me a headache. Ive searched throughout the internet for the labelling norms of AD but I can't find it. Everything that is explained relates to ADXXXX... something. No word about single char labelling.
