4.3 LA78040 VERTICAL AMPLIFIER
The LA78040 are power circuit for use in 90° and 110° colour deflection systems for field
frequencies of 25 to 200Hz field frequencies, and for 4:3 and 16/9 picture tubes. The IC contains
a vertical deflection output circuit, operating as a high efficiency class G system. The full bridge
output circuit allows DC coupling of the deflection coil in combination with single positive supply
voltages.
