DESCRIPTION
The TDA1675A is a monolithic integrated circuit in
15-lead Multiwatt® package. It is a full performance
and very efficient vertical deflection circuit intended
for direct drive of the yoke of 110o colour TV picture
tubes. It offers a wide range of applications also in
portable CTVs, B&W TVs, monitors and displays.
