LA7832
Color TV Vertical Deflection Output Circuit
Overview
The LA7832 is a monolithic linear IC for vertical deflection
output for small and mid-sized color television sets that
requires few external components and dissipates little power.
When used in conjunction with the LA7620 series of video
chroma deflection ICs, the LA7800 series of deflection ICs,
and the LA7850 series of display ICs, it is possible to create a
stable and compact vertical output deflection circuit.
Features
. _{High output.}
. _{Low power dissipation due to built-in pump-up circuit.}
