4-4 TDA835xJ Vertical Amplifier
The TDA835xJ are power circuit for use in 90° and 110° colour deflection systems for field frequencies
of 25 to 200Hz and 16/9 picture tubes. The circuit provides a DC driven vertical deflection output circuit,
operating as a highly efficient class G system. Due to the full bridge output circuit the deflection coils can
be DC coupled.
The IC is constructed in a Low Voltage DMOS process that combines Bipolar, CMOS and DMOS
devices. MOS transistors are used in the output stage because of the absence of second breakdown.
