描述 Description

GENERAL DESCRIPTION
The TDA4885 is a monolithic integrated RGB pre-amplifier for colour monitor systems (e.g. 15\" and 17\") with I2C-bus control and OSD. In addition to bus control beam current limiting and gain modulation are possible. The signals are amplified in order to drive commonly used video modules or discrete solutions. Individual black level control with negative feedback from the cathode (DC coupling) or fixed black level control with positive feedback and 3 DAC outputs for external cut-off control (AC coupling) is possible.FEATURES
• 150 MHz pixel rate
• 2.7 ns rise time
• Gain modulation capability for brightness uniformity
• I2C-bus control
• Grey scale tracking
• On Screen Display (OSD) mixing
• Negative feedback for DC-coupled cathodes
• Positive feedback for AC-coupled cathodes
• DAC outputs for black level restoration with AC-coupled cathodes
• Integrated black level storage capacitors
• Beam current limiting
• Analog subcontrast setting
• Pedestal blanking
• OSD contrast
• Sync clipping.
