DESCRIPTION

The TDA9115 is a monolithic integrated circuit as-

sembled in a 32-pin shrink dual-in-line plastic

package. This IC controls all the functions related

to horizontal and vertical deflection in multimode

or multi-frequency computer display monitors.

The device only requires very few external compo-

nents.

Combined with other ST components dedicated

for CRT monitors (microcontroller, video preampli-

fier, video amplifier, OSD controller) the TDA9115

allows fully I2C bus-controlled computer display

monitors to be built with a reduced number of ex-

ternal components.
