GENERAL DESCRIPTION
The TDA4886A is a monolithic integrated RGB
pre-amplifier 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 signals are amplified in order to drive
commonly used video modules or discrete solutions.
Individual black level control with negative feedback from
the cathode (DC coupling) or gradually adaptable black
level control with positive feedback and 3 DAC outputs for
external cut-off control (AC coupling) is possible.
With special advantages the circuit can be used in
conjunction with the TDA485X monitor deflection IC
family.
