Help needed to identify components on small DAC

I have a small DAC that I can't figure out a few parts. The DAC is based on the UDA1352TS. I am trying to find out what IC2, IC3, Ic4, and IC5 are. IC2 is labeled A3-LU. IC3 is labeled 7Z0AH (I believe). IC4 is labeled H80R. IC5 is labeled YJ then has a 66 (or 99) on it's side and then what looks like a p. Any help would be appreciated.
