The TDA4886A is a monolithic integrated RGB pre-amplifier for colour monitor systems (e.g. 15" and 17") with I 2C-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 of the TDA4886A 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.
