... NAME TDA4887PS SDIP24 2001 Oct 19 2 GENERAL DESCRIPTION The TDA4887PS is a monolithic integrated RGB preamplifier for colour monitor systems (e.g. 15" and 17") 2 with I C-bus control and OSD. In addition to bus control, beam current limiting and contrast modulation are possible. The IC offers brightness control with or without grey scale tracking for easy alignment ...
