Product Information

Ordering number:ENN2861A Monolithic Linear IC LA7836 Vertical Deflection Output Circuit with Driver for TV Sets and Monitors Overview The LA7836 is an IC that contains the vertical deflection output circuit with a driver for color, B/W TV sets, monitors, and display units with a large aperture (maximum deflection current 2.2Ap-p) and is placed in an SIP13H package. The LA7836 features fewer external parts and low power dissipation. Since both DC feedback and AC feedback can be provided inside the IC, it is easy to design the vertical deflection circuit. The LA7836 can be used in conjunction with single-chip IC LA7650 series (NTSC), LA7680 series (PAL/NTSC) (VIF, SIF, video, chroma, and deflection circuit) to provide all the functions required for color TV signal processing.
