LA7840 Datasheet (Sanyo) - Vertical Deflection

LA7840, Vertical Deflection

Ordering number: EN5147B 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’s LA7615 series of BUS control system signal processing
