DESCRIPTION
The TDA9112A is a monolithic integrated circuit
assembled 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.
Combined with other ST components dedicated
for CRT monitors (microcontroller, video preampli-
fier,
TDA9112A allows fully I
ter display monitors to be built with a reduced
number of external components.
