The TDA9105A is a monolithic integrated circuit
assembled in a 42 pins shrink dual in line plastic
package.
PRODUCT PREVIEW
This IC controls all the functions related to the
horizontal and vertical deflection in multimodes or
multisync monitors.
This IC, combined with TDA9205 (RGB preamp),
STV942x(OSD processor), ST727x(micro control-
ler) and TDA817x (vertical booster), allows to real-
ize very simple and high quality multimodes or
multisync monitors.
