Monolithic Linear IC
LA7840
Vertical Deflection Output Circuit
Overview
The LA7840 is a vertical deflection output IC for TVs and
CRT displays with excellent image quality that use a BUS
control system signal processing IC. This IC can drive the
direct (even including a DC component) deflection yoke with
the sawtooth wave output from the BUS control system signal
processing IC. When used in conjunction with Sanyo鈥檚 LA7615
series of BUS control system signal processing ICs for TVs,
this IC can process all color television signal system functions
through the BUS system. Because the maximum deflection
current is 1.8 Ap-p, the LA7840 is suited for small and
medium screen sets.
