LA7848

Monolithic Linear IC

TV Vertical Output + E/W Driver

with Bus Control Support

Overview

The LA7848 is a vertical deflection plus EW driver IC for high image quality TV and CRT displays that supports the use

of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC

can directly drive the deflection yoke (including the DC component). The LA7848 also provides a parabolic waveform

output that can similarly be used to drive the diode modulator block.

Functions

• Built-in pump-up circuit for low power dissipation.

• Vertical output circuit.

• Excellent crossover characteristics.
