2. General Description
The TDA8350Q is a power circuit for use in 90°
and 110° colour deflection systems for-field
frequencies of 50 to 120 Hz. The circuit
provides a DC driven vertical deflection output
circuit, operating as a highly efficient class G
system and an East-West driver for sinking the
diode modulator current.
