... C-bus 2 GENERAL DESCRIPTION The TDA4886 is a monolithic integrated RGB pre-amplifier for colour monitor systems (e.g. 15" and 17") with I 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 ...

... Signal input stage (input clamping, blanking and clipping) The RGB input signals with nominal signal amplitude of 0.7 V are capacitively coupled into the TDA4886 from a low-ohmic source (75 recommended) and actively clamped to an internal DC voltage during signal black level. Because of the high-ohmic input impedance of the ...
