Hello! I need some info on tech stuff...
Because of dead left audio, I tracked it down to the ESS chip on the concierto board. JJB checked also the resistors/tracks, but still no left audio from concierto... so I am thinking of replacing the ESS1688F chip on the concierto, I really want to save it and not bin it, it is a shame! :-(
only prob is that I have 2 good ESS1688F chips...
#1: ES1688F
D175 VB34197#2: ES1688F
D325 VB38567the concierto one is: ES1688F
D127 TAVBB9831Aanyone knows wth those Dxxx VBxxxxxxx markings mean? is it possible that the TAVBBxxxxx marking means different voltage or something similar???
any info is appreciated...

HERE is the 1688F datasheet in PDF format (thanks alexh !)
thanks! :-D
