FEATURES
85 MHz video controller
Fully DC controllable
3 separate video channels
Input black-level clamping
White level adjustment for 2 channels only
Brightness control with correct grey scale tracking
Contrast control for all 3 channels simultaneously
Cathode feedback to internal reference for cut-off
control, which allows unstabilized video supply voltage
Current outputs for RGB signal currents
RGB voltage outputs to external peaking circuits
Blanking and switch-off input for screen protection
Sync on green operation possible
On Screen Display (OSD) facility.

GENERAL DESCRIPTION
The TDA4882 is an RGB pre-amplifier for colour monitor
systems with SVGA performance, intended for DC or AC
coupling of the colour signals to the cathodes of the CRT.
With special advantages the circuit can be used in
conjunction with the TDA485x monitor deflection IC family.
