GENERAL DESCRIPTION
The TDA4887PS is a monolithic integrated RGB
preamplifier for colour monitor systems (e.g. 15" and 17")
with I
2
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. The signals are
amplified to drive commonly used video modules or
discrete solutions. A choice can be made between
individual black level control with negative feedback from
the cathode (DC coupling), or black level control with
positive feedback and three DAC outputs for external
cut-off control (AC coupling).
The circuit can be used with special advantages in
conjunction with the TDA485x monitor deflection IC family.
