TDA4850 Datasheet | NXP Semiconductors

FEATURES - VGA operation fully implemented including alignment-free vertical and E/W amplitude pre-settings - 4th VGA mode easy applicable (XGA, Super VGA) - Multi-frequency operation externally selectable - All adjustments DC-controllable - Alignment-free oscillators - Sync separators for video or horizontal and vertical TTL sync levels regardless of polarity - Horizontal oscillator with PLL1 for sync and PLL2 for flyback - Constant vertical and E/W amplitude in multi-frequency operation - DC-coupling to vertical power amplifier (TDA486X or TDA8351) - Internal supply voltage stabilization with excellent ripple rejection to ensure stable geometrical adjustments. QUICK REFERENCE DATA SYMBOL VP IP Vi sync supply voltage (pin 1) supply current PARAMETER - MIN. 9.2 TYP. 12 40 1 120 - 1.4 - 1.4 1 - - - - - - 1.6 - 1.6 - 60 70 GENERAL DESCRIPTION The TDA4850 provides economical solutions in VGA/XGA and multi-frequency monitors. The IC incorporates the plete horizontal and vertical small signal processing. VGA-dependent mode detection and settings are performed on chip. In conjunction with TDA486X or TDA8351 (vertical output circuits) both ICs offer an extremely advanced system solution.
