DESCRIPTION

The TDA9105A is a monolithic integrated circuit assembled in a 42 pins shrink dual in line plastic package.

This IC controls all the functions related to the horizontaland verticaldeflection in multimodesor multisyncmonitors. This IC, combined with TDA9205 (RGB preamp), STV942x(OSDprocessor),ST727x(micro controller)and TDA817x(verticalbooster),allowsto realize very simple and high quality multimodes or multisyncmonitors.
