Monolithic Linear IC
LA7848 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.
