Monolithic Linear IC
LA7800
Color TV Synchronization, Deflection Circuit
Overview
The LA7800 is a multifunctional IC containing various
functions required for synchronization, deflection of color
television sets. This IC has been developed under the de-
sign concept that the basic characteristics should be made
more complete and the television sets with this IC incorpo-
rated should be streamlined by making the device compact
(DIP-16) and by minimizing the number of parts required.

1.2
• Multifunction and compact (DIP-16).
• Minimum number of parts required.
• Horizontal and vertical oscillators are stable against varia-
tions in ambient temperature and supply voltage due to
small warm-up drift.
• Small variation in horizontal oscillation frequency.
• Good linearity and interlace because DC bias at vertical
output stage is subjected to sampling control within re-
trace time.
• Vertical blanking pulse width can be set freely according
to peripheral parts.
