LA7848

Ordering number : ENN7877 www.DataSheet4U.com Monolithic Linear IC LA7848 Overview TV Vertical Output + E/W Driver with Bus Control Support 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.
