DESCRIPTION

The TDA9105 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 vertical deflectionin multimodesor
multisyncmonitors.
This IC, combined with TDA9205 (RGB preamp),
STV942x(OSDprocessor),ST727x(microcontrol­ler) and TDA817x(vertical booster), allowsto real­ize very simple and high quality multimodes or
multisyncmonitors.
